I read all the horrible reviews but decided to try this site anyway - So glad I did. I sent them about fifty TI-83's that I felt were not in that great of shape. I expected to receive less than half of the quote I got on the website, but damned if they didn't send me nearly the whole amount. Yes, it took about 3-4 weeks total but I received payment with no problems and would definitely use this site in the future.
