I will never get any HD TV Set below 1080p. Samsung has the best priced DLP Sets so far. I have to tell you that the user interface is really bad it totally undermines everything else. The universal remote control that comes with won't even recognize its own DVR combo. But still I might snag another SAMSUNG 1080p DLP Set for my bedroom since I like to hook it up to PC. It is pretty cheap.
As far as Blue Ray concerned, I will wait out at least 8 month for the the price to drop and make sure they will prevail in the format war even I am sure they will due to technical merits.
I worked in (Data) Storage Industry as an engineer and Samsung was one of my offshore clients. They still have a long way to go but I'll pick Samsung over Sony anytime.
