It would seem the primary benefit to spending the extra $500 or so on the LT155 would be to gain MLA and some extra light output. But the 1000 hour lamplife of the LT155 is a major drawback. How bad is the screendoor effect in the VT540 and is the improvement with the LT155's MLA worth the extra investment. My viewing distance will be around 15 feet and would like to have somewhere around a 100" screensize. Also, how much can I expect to pay for replacement lamps on these two units?
Higher quality sources will be Dishnetwork 6000 HD and DVD via HTPC, but would also like to feed in NTSC. Are the built-in NEC scalers acceptable for line doubling the NTSC video.
Also, considering there is only one VGA input, is there an inexpensive VGA switcher that can be had to switch between the HTPC and dish6000.
