It's been awhile since I bought a new tv (3yrs). Need to upgrade from my JVC 27inch. I'm looking at these two:

JVC HD56FC97 56" HD-ILA PROJO HDTV
or
Sony 50" SXRD LCD Projection HDTV


Both are on sale and the same price this week. Any opinion(s) would be greatly appreciated.

The Sony SXRD line (which is LCoS, not LCD) has been very well reviewed by most people. Do a search on this site for the specific model number in question - they have been discussed a lot.
