I'm in the market for a new 32" HDTV direct-view tv, and am considering these two sets. Judging from the specs, they seem nearly identical. They even share the same cabinet. The only differences I could spot are: HS500 - DRC™ upconversion HV600 - DRC MultiFunction V1 upconversion (is this even any different)? HS500 - Twin View Picture and Picture with Multi-Image Driver X HV600 - 2-tuner PIP (standard and split-screen) ... don't know what the differences are here either HV600 has a HD Detailer wideband video amplifier and the HS500 doesn't Now is there any one feature (or more) that justifies the extra $200 of the HV600 model over the HS500?
