Sorry, alan-r, got to disagree with you there....
For smaller sized TVs, sure, go for LCD, but, even with the newer models out there, Plasma is still better for anything over 37".
OLED, as you say, should be the "next step", but they wont be worth purchasing until they become cheaper to produce.
Sandmaster, there is no way Plasma TVs will be getting "banned" by the EU - no idea where you might have heard such a thing....
Oh, and if you want a huge box sitting in your living room, then, yeah, go for a CRT - if you can find a shop still selling them! lol
As above, if you're looking for a TV over 37", i'd definitely suggest going Plasma - Panasonic or Pioneer, although a bit more expensive, are definitely the better manufacturers....
