Yeah, I'd have to vote for a DLP most of the time. Assuming you're not packing up and moving every few minutes, 'cause any kind of projection TV will not be as easy to move as a plasma/LCD/whatever, or if you watch TV under halogen spotlights (in which case you're probably going to want to go with a CRT or something with a picture that's hard to overwhelm), then a DLP is probably the best technology to go with. Unlike Plasmas and LCDs, with a DLP you can get a true black, sometimes even better than a CRT, without the electronic squal of a CRT, and without having to have a 600lb monster in your living room. Imho, DLPs are the best choice for general use. Plasmas are better if you're REALLY cramped for space, and CRTs are better if your living room is the size of a barn, but other than that...
As for brands, I'd recommend going for an RCA, since they're usually cheaper than the other brands, without being cheap plastic crap like, say, a Sanyo. Also, they're reasonalby inexpensive to maintainm what with bulbs needed replacing every few years and all.
Also, I'd definitely recommend getting a TV with HDMI inputs, since it's a pure digital signal and over the next few years it'll be the next big thing. Of course, you're also going to want composite, component, s-video, and an integrated tuner. The more inputs the better. Hooray inputs!
Hope this helps!
