Budget?

Panasonic is good bang for the buck. Epson is arguably the master of LCD, as they make the panels for pretty much everyone except Sony, and usually do a very nice job of engineering good heat management and durability along with solid picture performance.

Since your TV is DLP, you are plainly good with 1 chip, so you ought to look at some of those as well.

Looking for screen advice too, or are you going DIY?
