Hey Dean -
You mentioned that a G90 costs approximately twice what a G20 does (new). I haven't kept up with DILA prices recently, and was under the impression that a G20 was near $20k. If I interpret your post correctly, is the "street price" of a G20 now about $12k?
As far as bulb cost, it of course matters how hard you drive the projector. In the case of my current G70, I should be able to get (conservatively) about 7,000 hours out of the tubes, and replacing them is going to cost about $3,000 (again, being conservative here, as it can be done for less). Bulbs for the G11, as I understand it, are about $1k each, and last about 1000 hours. Therefore, for 7,000 hours of operation, the DILA will cost $7k, the G70, $3k, or roughly double. Using more realistic figures for CRT life and replacement, the figure is more like triple.
However, replacing tubes on the G90 is much more expensive, approximately $1500 each. I was under the impression, though, that the Xenon bulbs for the G20 run about $1400 and also last 1000 hours.
If this ain't correct, Dean,perhaps I need to re-calculate my costs and reconsider my choice of CRT vs DILA!
