I have the KDS-R60XBR2.
Can't really say much of anything bad about it.
Regular dvds through the hdmi hookup look amazing you can hook up the pc through a vga cable or hdmi input since there are 2 of those.
I was playing Bioshock and Portal on it yesterday, ran Portal at 1080 for a few minutes and it was beautiful, killed my compy playing it at that res tho. lol
Sound is very good compared to a lot of tv's I've heard treble is clean and the bass is actually pretty nice considering we don't have a system hooked up to it.
I guess my only beef is if you don't have HD tv channels the picture is stretched but other than that I love it.
If you can I'd find a store that will let you hook up a game system or dvd player to the tv's in store.
