Samsung HL-S5679W 56-inch LED DLP HDTV

Not the cheapest (which is normally a benefit of going rear projection) but it does get rid of the dreaded "rainbow effect" while still giving you a great picture. Overall, I'd say they like it…but in that $4000 price range, you've got a lot of options anyways, so may want to rethink this one.

Besides its exotic light engine, the Samsung
HL-S5679W 56-inch LED DLP HDTV is a full-featured set that delivers
crisp high-def pictures with rich, satisfying color — and no rainbows.
You're bound to find other DLPs that offer similar picture quality at a
lower price. But if you're itching to own a forward-looking TV — and
LED is sure to play a big role in TV's future — Samsung has your ticket
to tomorrow.
