NEED IDEAS FOR PRICE OF 60" TV

I have a Philips 60" Rear Projection TV that I am going to sell and I need some ideas on how much to sell it for. It is 4 years old in perfect condition and works great. It is not HD but has inputs up the wazoo! I love the TV but I am moving into a really small place and don't have a spot for it now. Any comments would be great. Thanks

maybe $800? dont really know for sure, but you can get a new 51 inch HD set for nearly a thousand on closeout at some places
