So I guess the 3 broken consoles are out of warrenty/have voided warrenty?

If thats true your in the same boat I am. I have a working 360 and an old out of warrenty RROD console that I don't know what to do with.

I would sell the games, not to gamestop though, like crr mentioned glyde. I just checked out glyde today and it looks like you can get good money for your games way better than gamestop. I'd estimate you could get $100+ for the games on glyde. The $50 bonus deal on trading in consoles sadly ended a day or two ago but if your real worried about your current 360 breaking and its out of warranty id see what gamestop would give you. Finally you could use the money you got from selling the games/ds and xbox to send in two of your broke consoles to Microsoft for repair/refurb exchange. Which would cost you $99 each and take around a month.

Or you could try to do what i'm doing. Call customer support everyday and try to get them to accept your out of warranty broken xbox and give you a free repair. But so far that has proven unsuccessful and frustrating as hell. Don't buy a ps3...reach, crackdown 2, gears of war 3, & what other games that Microsoft ends up finagling an exclusivity deal with.
