I would say improvements in motion and contrast are what I'm looking for, not so much sharpness at my seating distance. That kind of eliminates the NX series this year at least. The RS-45 may be old, but the image is still very competitive for my setup and at my seating distance.
At my seating distance, contrast is more important than sharpness, and my RS-45 is very sharp anyhow, the lens has 0 focus uniformity issue and almost perfect convergence. The most amazing thing is I'm at max H-shift and it's still almost perfect. One problem I had with the RS-67 and RS-640 that I tested was the lens CA was very apparent when I enabled max h-shift and the focus got worse when maximum shift was used, I tested it at the dealer. That is why I didn't buy it, it was a steal too, amazing price, but he was trying to get rid of it because it was a bad sample IMO.
I have owned around 12 projectors, the only projectors sharper than the RS-45 was the Mits hc7900/hc8000, the Benq w7000 (barely sharper, and I mean barely), and RS-45 is # 3 out of all 12 projectors. The Mits was king of the hill in sharpness if you got it in the right mounting spot, sharper than a Runco but not as sharp as a Samsung a900 (nothing is).
It doesn't matter how old the projectors are, the technology hasn't changed that much for JVC's other than the lamps and the now Native 4k. The RS-56/57 and 66/67 are too dim, as the RS-4x series was always slightly brighter. The RS-4910 was the brightest pre-RS-4xx/5xx/6xx series though AFIK. So I could go for an RS-4910 I suppose, but I don't know...
I'm looking for a deal on an RS-620 or RS-640 preferably, but I will also settle for an RS-5xx series. I just need to take some time and go hunt one down on Craig's list or the classifieds, but some people are asking way too much.
