DDR GB 2 : $60 shipped
Good condition, you don't really find these around anymore. I really loved it, but I don't play it anymore. The outside box is a little bit rough, but the ones inside are in excellent condition. The cartridge and dance pad attachment are both in great condition. The dance pad works really well.
IIDX 10th Style : Current bid is to a local kid for $45.
Box has a few nicks in it. Disc is in good condition. Game runs fine, NO songs are known to freeze.
Nintendo DS lite + 3 games : 140 for the DS + all 3 shipped, or 110 for the DS alone and 20 each for the games.
The DS is in great condition. I didn't play it very much, and it's not very old. Comes with the original box, all of the instructions, charger, stylus. There was an extra stylus, but I don't have it anymore. I would hope that's not an issue.
The 3 games are--
Pokemon Pearl
This has been played the most. The box and cartridge are both in excellent condition. Still has all the instructions and the poster thing and what not.
Xenosaga DS 1&2
I seriously have put about an hour of game play into this. It's not really bad, I just never really wanted to play it. THE CATCH: It's in Japanese. Have fun.
Super monkey ball touch
Fucking fun. I love it. It bought it used, though. Plays fine and the box comes with all of the instructions.
I'll try my hardest to get everything shipped out as fast as possible, but I've never sold anything via internet before so.. Hopefully everything goes smoothly.
