There will be a point where prices slow this huge rise they've been doing. Certain items will always be high priced, but I can't see 10 years from now, like in the example I made, "Magical Chase" going for almost $85K in 2025 or so. Then again, it could!
Vestcoat, in an earlier page, also mentions he noticed the prices rise sharply when the TG-16 stuff became available for the Wii. Same thing I noticed, and has been mentioned here before. All fo a sudden the TG-16 had a lot more exposure. It was a system, where even people who grew up during that time weren't familiar with it.
The way some prices are right now, there is a lot of stuff I wouldn't touch. Even about 10 years ago, when I wanted a system modded for S-Video and such, I went with a Duo-R, not only because I've noticed they tend to have less problems, but also the price.
The same with Neo Geo. I don't mess with AES. MVS only for me. I'll let other people play with those crazy prices.
Speaking of people who dump collections, I remember a guy here, I can't recall the name, back in 2006 or so, he spray painted his Duo-R black? He posted here for about a year after he started buying TG-16 again. Then, he sold it all on ebay.
