hey guys, I just thought I'd ask you opinion on this...my friend recently upgraded to a 67" Toshiba TV and is wanting to sell off his old projection tv. It's a Pioneer unit about 50 - 52" display and had projection parts inside replaced about a year ago. He's asking $750 ( canadian funds that is be roughly $480 american ). The thing is that it's around 7-8 years old. Is this a good buy?
