For those who're still interested in buying/finding a used BC PS3 ...
Since I'm a new member, I won't post the link unless people here say it's okay. But I found a reputable online retailer which seems to have the best price for a used BC 60GB PS3.
If your PS3 dies after the warranty expires, instead of paying $ 150 to Sony you could try one of these people who're charging half that
"Got YLOD? Don't give Sony another $150 + tax ... and lose your HD contents"...
In my opinion it's not worth buying a used BC due to the combination of $ 150 to Sony for repairs, the high cost of a BC PS3, and the fact that the YLOD seems to be limited right now to the BC PS3

I second the Typing of the Dead recommendation.
It's a geeky kind of fun. Each time a zombie appears on the screen, there's a word or phrase on his chest. You have to type that with a few seconds to eliminate him.
