I'm with
@AcuDefTechGuy on this one. The older model was solid, but has been significantly upgraded upon. The best direction, really, from a high end Epson is to go to something like a JVC model. Or, yes, at the very least, the LS12000 or whatever comes along later.
I expect in a couple of years, we may be far closer to $3,000 for the laser driven models that are near the quality of the LS12000 is at right now. Hopefully JVC will get their head out of their butt and put a laser in their lowest tier LCoS model and that will likely be THE way to go if budget allows for it.
