What do you want in the the TV? DLP is a nice alternative if physical size isn't important or you want a bigger screen for a reasonable price. If you go that route, you should also make sure glare isn't a problem with your viewing setup; DLPs can suffer because of their brightness level.
Do you plan on keeping the TV for more than 4-5 years? Will you use it as a computer monitor? If you answered no to both, 1080p is a waste. No console will use it much this generation and if you buy a 720p/1080i TV that deinterlaces properly, movies will look just as good in 1080i as they would in 1080p.
There are a lot of options in HDTVs and they all have their weaknesses... Expect a lot of different answers from people around here.
