Feeler for 51" Hitachi HDTV

My wife and I want to upgrade to a flat screen and I want to see how much I can get for my current tv. It is a rear projection, 51", 1080p, HDTV with built in tuner. It has one HDMI input, 3 RCA inputs, one S-video input, and some other misc inputs/outputs like digital audio etc. It is an incredible TV, but we want something that is a little slimmer since we don’t have a ton of room. The tv is pretty deep and we would like to reconfigure our living room. The TV is only a year and a half old, and it was purchased at Circut City with the extended warranty which still has about 6 to 8 months left on it. Let me know if you have any offers, we are still considering our options. Here is a picture (its small, but it is the best i could find online):
