Feeling out the waters for a PS2 or XBOX

[setaside]

My wife is wanting DDR for christmas so she can "exercise" so I thought I'd feel out some prices on a used PS2 or XBOX from the community. If anybody has one that they might be looking to get rid, shoot me a PM or an email with more info. I don't need a lot of games (or any really for that matter). I'm leaning more towards an XBOX because I like the game selection a little better but it's not a selling point for me.

Thanks.
