Best big flat screen under 4k

Dont know if in addition to "flat panel" you also meant 16:9 and HD compatible, but I, too, would be interested to know the best bargain in that category for a space saving solution in the bedroom.

I am told that prices have been dropping rapidly on the plasmas so there should be some bargains around.

Eric,

I've been hearing good things about the Samsung 43" and 50 " flat screen DLP projection TVs as well.

At a street price between $2950-$3500 and with a depth of only 16" and weighing only 68-80lbs each, they seem like real contenders without some of the negatives of LCDs or plasmas.

Have a look:

How reliable are these new DLP projector units? If you are to spend close to 4K, I would look into them. The Samsung DLPs look exciting, but I would get some sort of warranty. Still a new technology with some glitches.
Gunbei, do you know anything about the longevity of these units?

Gateway has some inexpensive flat plasma displays. Supposed to have HD versions out soon if not already. Never seen one myself, but I'm told they are OK.

Try the plasma forum at http://www.avsforum.com. Those guys are to video what a'goners are to audio. A couple of the names I keep hearing for plasmas in that range are Panasonic (might exceed budget) or Pioneer. The Pio 433CMX or 403CMX (or something like that) might just be the ticket for you.
