I like my 32x. As mentioned above, the better video encoder is a plus, especially with a Gen2 system, which aren't known for having the best video encoders. I'd never pay market value for one, but I got mine untested on ebay for $10, that's a steal for me. I dont' have a ton of games, I don't have Chaotix, but a few that I've got are still fun. Star Wars, NBA Jam TE, even Doom. I picked up a lot of about 5 games on ebay for under $10. Unfortunately, where I live, I've NEVER seen a 32x game or 32x out in the wild, so online is the only way to go.
If you sell yours now, you might find yourself wishing you had it, and unwilling to pay what they cost.
