Generally DLP are price slightly higher than LCD, but for the $2K CAN/$1500 US, you're looking at approximately a list of the following front projectors (prices in $US):
LCD Projectors
Sanyo PLV-Z4 - <$2K
Panasonic PT-AE900U - <$2K
Epson Cinema 550 - $2.5K MSRP, most likely less if getting direct quote
DLP Projectors
BenQ 7700 - <$2K
Optoma HD72 - around $2K
(just as an FYI because it is outside of the price range you mentioned, but I always like to know for the next price tier up what increase in quality do I get for the additional cost, you have to be the judge)
Between $2.4-3.5K DLP projectors
Optoma HD78DC3
InFocus IN76 (just released recently)
Samsung SP-H710AE
Mitsubishi HC3000
Sony VPL-HS51A - **LCD**
There are other front projectors definitely below your price range, but they are not 720p native resolution and therefore not considered true HDTV-ready. Hope that helps. Others can chime in and add to my list if I missed anything.
