What do you think?

Looks slick. Maybe you could compare the price of that particular TV make/model online and then reduce the price a bit for usage. Or just use the prices you find and sell them for that. You could even mark up the price as long as you play the game right and sell it in the correct fashion. Another thing you could do is sell it for how much you paid when you got it. Seems like a fair way to do it as well.
