So I went back today to try and get it for $50...
I walked up to the guy's table and asked if I could see the top-loader NES. As he was getting it out he told me that he was selling it for $80...
Needless to say I was a bit shocked, and when I told him that I was there yesterday and that he had offered to sell it for $59, he acted like he had no clue what I was talking about. I figured that the guy was going to give me a hard time, but I figured "what the hell?" and offered him $50.
To my surprise, he accepted without skipping a beat!
The console was a bit dirty, and he couldn't find the A/C adapter, which I can replace easily, so I convinced him to throw me an NES Max controller and a copy of Commando, which were both filthy as well.
I cleaned everything up once I got home and it all looks perfect! Finally, my quest for the NES top-loader has come to a close! I'll try to post some pics later, I just have to find the digital camera...
Ha! That's a good one, I'll try to use it... I do know that if it has any cosmetic damage I'll bring that up. It looked fine when I saw it yesterday, but I didn't get a good up-close look at it.
