Look at a 50" Panasonic plasma if possible. I would challenge you to find an LED-LCD with better PQ at the same price point. I've seen the S2 for < $900, FWIW.

I believe some brick & mortar stores like Sears sell it too, which can sometimes make things easier for model comparisons/returns/exchanges/etc. YMMV. If you don't need a THX certified panel or built-in ethernet port like some of the slightly higher priced Panasonic plasma models, it may be the way to go.
