No one is going to trade a PS2 backward compatible PS3 for what you're offering. The last time I saw a 60GB PS3 on sale, it was going for $400.
Sell enough things on Craigslist (your PSP and the accessories, without the games, would probably be enough)to come up with the $150, get your 60 gig repaired, and play P3 for a few weeks on your old PS2.
