This morning I found the Optoma HD20 at Amazon for $869: http://www.amazon.com/Optoma-HD20-Definition-Theater-Projector/
with free shipping. In addition, it looks like you can buy it from an
Worldwide Distributors for $851 with free shipping via Amazon.
A word of caution: I looked at Newegg and the HD20 is out-of-stock.
According to Newegg, the HD20 may be discontinued (although, I think that is
Newegg's standard language when something goes out of stock). I searched
online and could not immediately find anything that indicated the HD20 has
been discontinued. Regardless, from my research, the Optoma HD20 seems to
be a very nice entry-level 1080p projector. See reviews here: http://www.avsforum.com/avs-vb/showthread.php?t=1165581
