I'm considering replacing my recently failed 15y/o Mitsu VS585R with a new model - went today to Best Buy and it seems they only handle the Silver line of their rear projectors?? Is Platinum or Diamond worth the extra for someone who is in a small town and has no access to HDTV cable broadcasts (or satellite, for that matter - no clear southern exposure)?? I've heard outstanding things about their Diamond series, but it's really far more than I wanted to spend. One of my main concerns are these "glossy screen protectors" the rear proj. TVs have nowadays.. so much light reflects in them, and they say the Mitsu ones are easily removable?? I questioned them about LCD sets as well, which deliver tremendously impressive HD images, but I'd be watching mostly analog cable signals & DVDs...also, they told me the lamp in them has to be replaced every 5 to 6 years, at cost of anywhere from $250 to $800 a pop, which to me seems a bit much, considering what you'd pay for an LCD set to begin with... If I *CAN* get my 15y/o set repaired - either the convergence board or a CRT will have to be rebuilt - it will end up costing me $80 for evaluation + $400 or so plus tax for the actual work.... is it really worth it if this is a 15y/o TV? Help!
