I got a 42" plasma ED set, I liek the picture better than any of the HD sets for the same money. its a monitor, so no tuner I have to have it pluged into cable, or a PC.
I would buy a LCD or a DLP projection system but you have to like it with your own eyes. The "screen door" efect is distractiong on most of the HD sets so I don't find the "higher res" to be better. an ED set with component DVD and cable input will blow you away and save you $500 on the set.
I think HD needs to settle down into a standard, they are on the 3rd "upgrade" and the shit isn't evan mainstream brodcast yet for another 8 years? let HD syncronize into 1 product line, 1 format.
