Based on my experience, it would be worth waiting a little time and get the money to buy a DLP unit.
When we bought our projectors, we tried everything and DLP was the definite winner in terms of colour rendition and image quality. LCD is meant more for Powerpoint bar chart presentations and tends to oversaturate the colours.
DLP delivers the most pleasing images.
We use NEC LT260 projectors which are equivalent to today's LT245 in terms of power. NEC has a sealed optic block (no dust can enter between the lenses). Also, the lens has threads, it allows the installation of a UV type filter to protect the lens just like on your camera lens. They are XGA and their contrast ratio is very high, something highly desirable.
Colour is infinitely adjustable so you can select the best rendition and match it to the profile of your computer screen.
I checked at this URL and the LT245 was 1,895USD (http://www.projectorcentral.com/online_prices.cfm?part_id=2630&trig=1)
I recently looked at the microportable DELL 3400MP projector which, for its size an price really impressed me when compared to larger units. It is a DLP XGA projector with a 1500 lumens rating (in practice closer to 1200).
Hope this helps,
