I bought the Samsung HLN467W 46" DLP and am very satisfied. Nice bright picture and wide viewing angle (important for my room) although the black level isn't as dark as I would like it. I looked at LCD RP sets (Sony, Panasonic) and decided against them due to some space constraints (wider exterior dimensions vs. the Samsung).
I heard the next generation Samsung's will be out by the end of this year with the 3 chip DLP, eliminating the color wheel that gives the raindow effect some people notice. I am guessing they are going to be expensive as hell.
Good luck with the TV purchase...looks like you've got a great setup with the audio end.
