ebay would be your best bet or buy and sell.

Yeah, definitely Ebay, there are used/broken ones on there that get bought all the time.

i popped mine opn ebay someone bidded 35pounds.........id keep ur extra controller and put the unit on ebay it will deffo sell

Yeah, eBay is your best bet. People buy them for parts and repair so you at least get something for them.

If you want to be shady, what do you mean by dying?

Does it still turn on and work?
if it's RRoD, have you tried the towel trick?

If you can get it to run you can still try one of the Gamestop type places. Either way they will send it to the refurbishment center.

Sounds like E74 to me.

Good luck on ebay man, you're sure to get some good money.
