WRONG
I can tell you from personal experience that Radio Shack does NOT sell the appropriate adapter for a CDX. You need 9.5 volts. Radio Shack cannot help with this.

AGAIN WRONG.
I went on my own expedition to find a power supply for my CDX. Neither a 9 volt nor 10 volt power supply will make the CD drive work properly. If you buy the wrong power supply, only the cartridge slot will work; the CD drive will freeze up mid-game.

As for the OP's question, I'd say no. Anything that's listed on ebay as "untested" or "as-is" is just plain broken. If you buy those Sega CDXs, I'll bet you dollars to doughnuts that the Genesis Cartridge slot will work, but the CD drive will not load CDs.

Well... even if they do happen to be broken, you're getting two. Which means it may be possible to get one working by exchanging parts between them.

Sigh.

As I already said, any 9v or 10v adapter that outputs 1.5a will work just fine with the appropriate sized plug.

No need to be a jerk about it.

I'd say yes. Even if they're both broken, you could probably assemble one working unit out of the two.

WRONG YET AGAIN
I'm sorry to be a jerk, Irixith. I believe that you mean well, but I'm more concerned with stopping the spread of misinformation--the misinformation that you are continuing to spread. I can see that you have some understanding of electricity. In theory, a 10 volt 1.5 amp power supply should work. I learned the hard way that it doesn't. I wasted a lot of time and money on the notion that I could fudge the voltage as long as I had the amperage correct. I told myself things like, "The device will only draw as much voltage as it needs." I was totally WRONG. CD-ROM drives in the '90s were very finicky. The CD-ROM drive in the CDX will skip, freeze up, fail to boot, and generate all manner of headaches unless you find a power adapter with exactly 9.5 volts and 1.5 amps.

Learn from my mistakes: 10 volts won't work; it has to be 9.5 volts.

I guess I must be imagining that the generic 9v 1.5a adapter I have plugged into mine works. :)

samsonlonghair, there's the possibility that there's a problem with your CDX unit. However, I really don't wanna jump into the middle of this. I'm not taking sides here. :D


That being said, here's a little tip for any one that needs an AC adapter for anything. The unit should specify the requirements (ex: 9.5v, 1.5A, polarity). Just go on eBay and search "9.5v AC adapter" or whatever and you'll get butt loads of results. I found a couple of sellers that dealt in ONLY used AC adapters. Here's the best part, you really only have to be concerned with the volts and amps, the size of the plug and polarity really don't matter. If you can find a junk AC adapter lying around the house that has the correct barrel size, you can just use that. Otherwise, Radio Shack has just about every size under the sun. Polarity doesn't matter cause you can just wire the new plug up tip positive or negative - whatever you need. Even if you score an AC adapter with the correct barrel size but the polarity is wrong, just cut the wire and switch them around. Simple! And since this way most of the time you're gonna find auctions for AC adapters for an HP scanner or old Epson Stylus printer, you'll be able to get it for like $5. Much better than wasting time trying to hunt down an adapter, and paying $10-30 for it. Especially one from Radio Shack, they have inferior products.

So for all of yous that think it's impossible to find an AC adapter with the correct barrel size for the CDX, there's tons of 9.5v 1500mA AC adapters on eBay. Just pick one that looks good. Bring your CDX down to Radio Shack and match up a plug for it (unless you got one lying around the house). Cut off the plug, and twist/solder the new one on. Just make sure you got the polarity correct. Easy as pie.

I've been looking for a CDX for some time and think my odds are pretty good that at least one works. If not there are a couple places in town that to retro game repairs. What do you guys think? If I buy them I'd likely sell one on here.

I'd say go for it, but only if you don't mind the risk. Or only if you're handy with repairing stuff like this. I look at it like this: There's two of them, chances are good that at least one of them works. In the event that both have problems, the chances are good that they both don't have the same problem. You could use one to repair the other.

In the event neither works, and you're not able to do the repairs, you could just resell them on eBay for a loss. At least in the description you'd be able to specify exact WHAT is wrong with them, making it more likely for some one to buy if they're looking for parts to repair another unit. Might have to take a small loss here since it's not a "may or may not work" gamble that you're looking at now, but at least you wouldn't loose the full $82.

You've hit the nail on the head. I've been thinking it over and the worst that could happen is that I might lose $20 or so after selling two defective units. On the other hand I could get lucky and have 2 working CDXs for a great price. Even if one of them is broken, $82 is looking like a great price for a CDX. I'm going to buy them and keep you guys posted. Thanks to everyone for the great input!

Just keep in mind that the CDX is packed tighter than a 10 year old vacuum cleaner bag and not easy to work on. I opened mine up for cleaning when I got it as I do that with all used video game I get, but took a look and just put it back together out of fear of breaking it since it was working just fine. Normally I disassemble completely so I can scrub cases in the sink and whatnot, but I left the CDX alone.
