I have these:
Samsung 47" LED - Paid $770 no tax
Samsung 51" Plasma - Paid $530 w/tax
Sony Bravia 32" LCD - Paid $390 w/tax

Both Samsungs are about a month old. The Sony is 3 years old.
The Plasma is a beast. 51 inches of HD thrust. Plasmas are cheaper and they come in large sizes!
Just make sure to get a good brand, and if posible buy from amazon.
My 46" led had bad pixels, but i called Amazon, and they sent me a new tv! Plus you avoid paying sales tax.

Yeah, anyways i like my plasma... but my go-to tv is the led.
