I also bought an Epoch on eBay -- probably from the same person -- and am quite happy with it. Even blown out to a 10-foot diagonal size the picture looks great, no pixels visible at 20 foot viewing distance and the brightness is quite good.
As the above poster noted, the input options are excellent; and, though I dismissed it at first, I find the motorized zoom/focus INCREDIBLY useful.
It does have some of the black level issues that all LCD FPTV's have; but I continue to be very happy with the overall picture quality. Anamorphic DVD's look great. I have yet to try a grey screen with it.
I would recommend getting an outboard line doubler or quadrupler to use with it, however. I use an iScan v.1.
