I have a K790a that I bought hoping to fix it, but I couldn't. There are still many usable parts though. The phone's cosmetic shape is perfect and I believe everything but the phone itself works. I never got it to power on though so I can't say for sure. I'll take $60 shipped.
I also have a K610i that I bought from somebody who said that it got unplugged in the middle of a flash. I have not got it to work. The phone itself is pretty beat up, but the LCD looks good and I'm sure there are other usable parts. I'll take $40 shipped.
