I saw both the HS2 & HS10 many times at CEDIA earlier this week, both were very good. The HS10 is worth paying the extra for. Much smoother higher resolution image with less screen door. Having said that IMHO the HS2 is better than the AE100. Colours and contrast ratio on both were excellent.
Also had a good look at the Sony VPL12, Plus Piano Avante, Toshiba MT8 AKA Infocus Screenplay 7200, Philips Garbo & Sharp Z90U.
Some great projectors are coming.
Hope this helps.
