Original/Slim, 40GB-320GB, with or without controller, backwards compatible or not, etc... What would be a good price for a used PS3 on eBay (or anywhere)? Does the PS3 have any kind of Xbox 360 red ring of death-type problem that I should be weary of? Is there any improvement or step backwards other than backwards compatibility with the PS2 that I should be concerned with? Finally, is this even a "good" time to buy a used PS3 or is there talk of an imminent price drop around the corner?

Thanks for the shared expertise.
