actually I think 60hz lcdtv's look the best. with a decent response rate (5-6ms) there's not going to be any motion blur / ghosting
the 120/240hz tv's, a lot of them get image stutter from the processor which I think looks a lot worse than the motion blur from the older generation 8ms+ response 60hz lcd's. the 120/240 tv's are just a big sales gimmick and completely unnecessary once the pixel rate itself is fast enough to keep up. they sell it for home theater because people will spend money on it but all your desktop monitors are running at 60-75hz and look great assuming their response rate is quick enough
imo a good lcdtv is the best way to go right now (for an actual tv), until OLEDs become affordable. plasmas are so reflective, the glare would drive me nuts. and LED tv's are just a stepping stone to lasers or oleds anyways
