I have seen the Sanyo PLV-WF10 and am seriously considering that for our living room with it in a fan ventilated enclosure...
4000 lumens - after calibration
900:1 Contrast
$12,995 MSRP - A lot less on the street.
It is a loud projector though and either must be rear projection or in a separate room (movie theater style) for front projection. But, there are many lenses available for it.
Plus it is a 2 bulb model, so if you don't need the lumens, you can run just one bulb and have one spare, in the projector, ready to go at all times.
Will look forward to reading some reviews on the Vidkron though.
