[quote name='JJSP']Zew/Brak, what should I expect to get for it? It's launch-ish (no HDMI), unbanned and never been opened. It's been refurbed two or three times I think - even running shit off the hard drive (installed games) sounds like it's ready for liftoff after a half hour or so.[/QUOTE]
I did it a while back, before any significant price drop... I didn't sell mine, though. I traded it in at GameCrazy on a Black Friday, and picked up an Arcade (with HDMI).
I can't imagine 360s fetching a lot at GameCrazy or GameStop, these days. But, if your drive was as bad as mine, it'd probably be best to trade it in and forget about it, as opposed to selling it to someone and worrying about them shooting you in your driveway.
