SVGA is sufficient, normally. Taking into account that you don't want to
overwhelm your audience for very fine details on a transparency anyway.

If I'm not mistaken dlp has generally a bit more luminance than lcd,
which is always welcome. At the university we have several brands, of
which I like 3M and Epson most. The last one is much smaller...

Do calculate into your budget the cost of exchanging of the bulbs. I've
heard exorbitant prices, availability problems, etc. I think the
projector biz is trying to copy the printer world: sell the peripheral at
cost, then compensate with the parts (ink/toner cartridges or,in this
case, replacement bulbs).

Average lifetime is 1500-2000 hours, taking very good care of the
projector (no vibrations, correct switch-on/off etc). Say 200 days at
8hrs/day.
