I believe the model 2 uses a 2.5 Amp fuse, so a four pack would $2.99.
According to the retrocorner, it uses an 850mA fuse. I don't know, maybe a 2.5 amp fuse would work as well?

I would go with that. A higher rated fuse means it will take a higher current to blow the fuse in the future, not what you want. The fuse blows to disconnect the circuit before the power surge reaches something important. Get a fuse that's rated too low and it will constantly blow during normal operation, get one too high and it won't blow when it needs to. I keep reading conflicting things online about what the Sega CD model 2 fuse is supposed to be rated. Disclaimer is I've never replaced the fuse on a Sega CD, but I have replaced it on an SNES, and its the exact same type of fuse, which is why I'm not positive of the fuse rating. I've seen a lot of people recommend a 1.5 Amp fuse as well, that might be a good compromise, unless anyone can chime it with the Sega factory spec rating. A 1.5 Amp fuse should cost the same as the 2.5 Amp.

Update: I tried to fix the Sega CD by doing the fuse replacement. The sodering was frustrating and difficult, so I cut the fuse off and twisted the wires together. I tried and tried, but it just wasn't working. Partly because I couldn't find the reccomended fuse, and had to try it with a giant automotive one. To make up for the lost fuse, I put the SCD on a surge-protected power strip. Anyway, the SCD works perfectly now. Too bad all I have to play on it are the two lame games that came with it, Jurassic Park and MegaRace. Thanks for the help.

The size of the fuse doesn't matter, but the amperage at which it blows is very important. You need to have matched that. If yours it not the right amp rating, you should replace it with the correct one. If you matched that, it is fine if it is a large glass fuse or a flat blade fuse.

The idea was to buy a fuse holder and solder the wires to either side of the old fuse, then you just pop in a glass fuse into the fuse holder, making it easy to replace again without soldering.

Yeah, that's what I was trying. But the fuse holder was huge, and the wires fat. I just couldn't seem to get everything connected in the area provided.

Yep, not copy protection whatsoever. Like most early cd units. The PS1 was the first cd based console available with cd burners were actually affordable and popular. During the Sega CD, 3DO, Philips CD-i time they weren't really affordable to most people, so there was really no point in spending the extra money and hassle to protect against them.
