I'm in the market for one myself, and I've narrowed it down to a 50" Plasma with a built in DVR by LG, a 50" plasma with ambient lighting system by Phillips, and as a backup, a 50" plasma by Panasonic, just because they seem the most reliable.
If anyone knows anything about these tvs, info is appreciated?
Don't buy phillips. They cut alot of corners and unless you're looking to buy a new tv in two years, I wouldn't shell out the dough.
For TV deals, just scout at slickdeals.net forums. I haven't bought any electronics at retail since high school.
