If you've got a PS3 and you no longer use it, I'd be happy to take it off your hands. With the looming PS3 price drop, I probably won't pay more than $275 for a 80GB.
I'd say that you are dreaming if you think you can get a 60GB for that little. The price drop probably won't affect the price of used BC PS3s. It will drive down the price of used non-BC ones, but the demand for BC in constant and the supply is limited. I'd recommend biting the bullet and buying a used 20GB from gamestop and swapping the hard drive. You can get a relatively cheap replacement hard drive fom newegg.
Good luck though.
I guess he is right. I assumed he wanted one for BC due to asking for a 60 GB one. I guess that's what we get for assuming. I wish you luck. I want one too.
