Sony Grand WEGA KF-50WE610 50-Inch HDTV-Ready LCD Rear Projection TV
Been great so far (knock on wood)
I have owned this TV for a year and a half now and couldn't be happier with it.  I use it heavily in every day operation and have rarely had any issue at all.  The picture is outstanding, the sound is good, it was everything I had been looking for in a large screen TV.  I am dismayed to read many of the negative reviews though and only had one real wierd thing happen with it.  One evening, after turning it off, I couldnt get it to come back on.  I later realized the lamp was still on with the set off.  I cut its power at the surge protector, turned it back on and no problems.  Only issue in a year and a half.  It even survived being sold off by my ex-wife to some kid who drove off with it in his pickup.  I had to show up with a Uhaul van, pay the kid what he paid (like in Risky Business) and haul it to my house.   Still gives me everyday excellent movie and sports viewing :)    Wish it had an VGA connection but was not what I was looking for when I purchased it so no gripes there. :)    EDIT: It has now been over 3 years since I purchased this.  Using it heavily for movies and my Xbox 360.  Nothing troubling to add to what I typed above.  It still performs wonderfully.    EDIT Part 2: Now it has been 5 and a half years.  The lamp finally went out after having lasted longer than I was told it would.  Replacement lamps are much cheaper now however and otherwise, its still been wonderful.  Movies, Modern Warfare 2...its all good.    EDIT Part 3: Dec 2010:  Still most happy and new news to report.  With a decent video card and the DVI hookup in the back, I've been able to hookup the computer to the TV and resize the desktop using the vid card's settings.  Pretty much 99% perfect regarding resolution and will try to use dual link cable and perhaps push it further.  So that last bit of functionality I wished it had is now not an issue, I was just using an inferior hookup previously.
