This LED projector has been out since last year and needs it's own thread, so here it is without further ado ! The main selling points were the price, 720p HD and 30,000 hours LED Light source. No need to ever buy lamps and no toxic Mercury to worry about, the LED projector is a much GREENER enviormentaly safe and friendly product. I have been using the iSival projector now for well over a month and for the $499 price tag I'm happy to say it delivers despite what many will think mainly due to it's low contrast ratio and ansi lumens. The main competitor I'd say is the LG HS201. I don't own the LG but on paper and from user reports it offers rich colors. The inherit problem with the LG is the 800x600 resolution which further gets reduced when displaying 16:9 ratio content. I think it's fine for DVD and standard definition television broadcast signals but when it comes to PC Gaming, Console Gaming, and Blueray standards it falls short..It's a trade-off between contrast ratio and resolution when you compare the two. The iSvial is true 1280x768 pixel count resolution so PC games which is what I play look good on it. There is no visible screen door effect to speak of, even at very close distance. In a light controlled room the 60 ansi lumens gets the job done at 72-100 inches tested so far. The screen at 132 inches is the official maximum size the LENS can properly produce and correctly focus so it's more than enough for the average person. The projector passes the standard greyscale tests and I'd say have good image uniformity. The weakness would be Standard Def content, HiDef looks so much better and seems to handle dark movie scenes better than SD content. There is a green tinge on very dark movie scenes, not sure if it's my HDMI color settings but it is there but not a deal breaker. No input lag to speak of, tested playing Guitar Hero World Tour. The sharpness is decent but far from perfect, colors look good, but doesn't compare to my older Panasonic Tau CRT 1080i HD television (it beats most LCD HDTV on the market and even Plasma sets in my opinion)..but good enough considering the price...And now the rainbow effect..You don't see it much at all with movie content, even during rolling credits
...It's a non issue really. It does however appear in First Person Shooter videogames whenever you pan the camera quickly, but you get used to it..I think all single chip DLP projectors have this issue to some extent regardless of color wheel speed. Most other types of videogames such as racing games, adventure games, role playing games don't exhibit much rainbow effect. On a last note, every person is different, some people are more sensitive to this issue, so you have to be your own judge on this matter. The iSival is a good stop gap solution untill real 1080p LED projectors hit the market..
Here are test images I have compiled. Note that the camera pictures are just examples and that the image is indeed much better looking in real life...some shots zoomed in, no ambient lighting unless noted

And finally a little bit of info. I was told by a representitave of iSival that currently there is a 1080P LED prototype inhouse, no release date but this means 1080P at hoefully an affordable price will be a reality in the not so distant future..
