I have recently moved to Colorado and am looking to finally buy a new set. Talking with some surprisingly unbiased sales people I learned that Plasma sets are a mistake here because of the higher elevation. Apparantly it does something to the gas which causes noise through the speakers. I wasn't thrilled about the screen burn-in potential anyway. As for LCD's, they just don't look good displaying fast motion images. That leaves me with direct-view tube and rear projection. Tubes seem too heavy and you don't get as much screen size for the price - and rear projection is almost unviewable in a room with even moderate daylight (which is where my set will be). In looking at the Samsung DLP sets, however, they looked fairly bright. So I was wondering if these do any better in a daylit room. Just FYI, 50-55 inch sets are probably my limit (due to physical space restrictions) and the room will have very large windows which I can only cover with horizontal blinds (I can't hang blackout curtains or anything similar) and which will face towards the set (on an angle). Also, is there or isn't there a difference between the HLN5065W and HLN507W other than case color? I've read many conflicting reports over whether or not the 65W really has a cheaper chip inside. How can the 7W be ~$500 more MSRP if the guts are the same? Any advice or info would be appreciated.
