I haven't had to sell that many old console+games so I'm just going off gut feeling here. However, I wouldn't sell the items individually as you're not going to sell all of them and be stuck with some crap games you wanted to get rid of in the first place. For the PS2 bundle, I would shoot for a $350 mark and then see what contacts you get, that's not too far fetched as you have 40+ games and accessories. I would empasize some of the better games that you have in the bundle, specifically the Guitar Hero games, Need for Speed games and GTA.
For the PS1 bundle, I wouldn't expect to sell it at all
but I could be wrong. Start at $225 and accept offers?
What does anyone else think?
