It's getting to be time for me to think about a new TV to replace my venerable Toshiba 31 inch CRT. It seems that RPTVs have the best bang for the buck these days in terms of 16:9 HD compatible sets, but I'm curious as to their drawbacks. How frequently do projection lamps need replacement, and is that a costly process? Most sets I've seen also have fairly hefty audio systems, which I don't need as I have a fine audio system. Can anyone recommend a good model that concentrates on the picture? I'm looking in the $1500-2000 bracket but would be willing to go higher for sufficient return on that investment. Size of the screen is secondary to PQ. It's amazing that so many retail chains seem clueless about what they sell (and set up their products so poorly as well!). Thanks for any input that may help me make this decision.
