I saw the 510 again this week at a venue in NY. NEC had it in a small room shooting on the same screen as the HT1100. It was a white Stewart screen, think they said 1.3 gain and 92". They were showing DVD and some Windows MediaPlayer HD content. The 510 looked pretty good. Colors were pretty good, better than a unit with a 4 segment color wheel. The HT1100 looked better of course, with deeper blacks, more saturated color, and a smoother looking image that it is known for. I would guess the yellow segment in the 5 segment wheel helps video/movie content that should be run closer to 6500K. They said it ships in Nov. The 410 is shipping now in US. If you need to stay under $2K and are using it primarily for HT, I think it looks good. I would also suggest using a good progressive player as it does not have the video processing that is in the HT1100. Maybe a unit with the Faroudja FLi2310. It is also an attractive unit for people with low ceilings as it has the lens shift dial. If you can afford to move up to the HT1100, then do it, it still looks really good. (They did not have the anamorphic lens on it, probably due to position, it was sitting below the HT510 on another shelf) The room was not totally black, they had a plasma, with a curtain between to keep the light down for the projectors. They also would turn a couple of recessed lights on during conversations. The 510 hits a nice price performance point below the HT1100. The Windows MediaPlayer HD content looked great on both. If you are in the US and only need a unit for DVDs (480p), there is the HT410 and all the other units out there for $1500 that are 480p vertical res (also SP4805, etc..).
