I would strongly consider the H79 in the under $10K price category and then include the Z12000 in there as well.
More likely, since I really can put my projector exactly where I want it and am not locked into needing a heavily adjustable projector, I would get something more along the lines of the Sharp Z2000 which uses most of the same level of quality and technology as the Z12000 - except it is closer to $3,000 or so. Likewise, the InFocus SP7205 is the way I would be looking over the 7210. At well under $5,000.00 it's a great way to go.
