I'm thinking about getting a DLP TV (probably a Samsung HL-S5087W or 56)...

Any thoughts on DLP monitors?

We have HD service, but we mostly watch SD stations (that's one reason I'm leaning toward the 50" instead of 56")...

I'll probably be switching over to Dish Network soon, as well My Cox SD signal is awful on my 32", I can't imagine what it would look like on a bigger TV. Dish is supposed to have the best clarity of any carrier. (plus I don't get Fox or CBS in HD; I need my HD football).

(really, I mostly want to play xbox 360 on a bigger screen )
