My local Circuit City has both the Sony 34XBR800 (floor model) and 36HS510 (in box) listed for approx $1800. In researching these two, I'm a bit torn about which is the 'better' set. This is my first HDTV-ready purchase. I'm leaning toward the hs510 for no better reason than that the xbr800 has been discontinued. My main concern is that the 36hs510 may be missing some key piece of technology that I'm unaware of. The 16:9 format of the xbr800 looks great, but I figure it shouldn't be the deciding factor. I'll be using the tv for network programming through time warner digital cable and viewing dvd's. Any suggestions? Thanks, Derek.
