I was going back and forth between these projectors and luckily a local showroom had both setup in the same room! I'm an occasional 3D viewer as well but for me the RS45's 3D just isn't usable, I saw a lot of ghosting and would watch same 3D BluRay on the Epson and see none. Also the Epson is much brighter than the JVC in 3D. We did a lot of A/B comparison of black levels between the JVC and Epson on dark movies like Underworld and the bottom line is to us they both look great. There both great projectors but if you were doing 2D only I'd say the JVC is a great choice as well. The shadow detail the Epson did in Underworld was quite impressive yet still providing excellent blacks. So we bought the Epson and there is no looking back, we've had it about 6 months and LOVE LOVE LOVE it. I know JVC has had a history of premature lamp dimming, not sure if it's fixed on the RS45 but that was a concern as well considering how expensive the JVC lamps are compared to the Epson.
