Wah?
Most systems on eBay are still going for alittle over $1,000 why would you want to return it? Make a 400+ dollars in profit and be happy with it. If I could sell a PS3 I would, because even a few hundred dollars can get me 5 or 6 new 360 games.
Hell even Wii's are scoring 200+ in profit, although I'm sure that will change soon.
If you want to risk it, wait alittle long before Xmas week and I bet the price will go up again.
Either way your still going to make a few bucks going the eBay route.
