I have seen the Sim2 M150, Sony VW1000ES, the Marantz 11S1 and currently own an IN83 which is one of the brighter single chippers. The M150 is definitely brighter than the 11S1, I saw the M150 on a 110" screen with the lights off it looked great, with a couple of low lights on, still OK for TV viewing in my opinion. From the reports of the Cine 1000, it seems to perform similarly, perhaps even brighter.
I have the Sharp Z15000 which is around 1000 lumens with a new bulb, my IN83 is noticeably brighter. Its rated at 1600 lumens but ProjectorReviews measured it at around 1700 with contrast set to default. It is an order of brightness better than the Z15000. I tend to watch the IN83 with lights on a lot of the time and for me, it does a decent job. From seeing the M150 I was considering it to be a viable alternative but would probably need a screen with a bit of gain. You'll notice an improvement in colour and contrast with an LED, plus lack of a colour wheel - its hard to go wrong.
The Sony VW1000 looked comparable in brightness to the IN83 and from what people are saying the VW500 is very close if not the same. The VW1000 was the first non-DLP projector that I have been tempted by in a while, it has a DLPish look to it, for want of a better term
Now I would be the first person to tell you to demo a projector before making a decision and not to rely on screenshots but if you look at the screenshot thread, you can see a comparison of images from Life of Pi with a JVC and the Sony. I might give you some impression of what to expect from the Sony.
I would say if want to keep the DLP look but with some higher brightness and other improvements go for the Cine 1000. If lumens are of a higher priority, you fancy something different with improvements in contrast, look at the VW500. In my opinion, an Epson, JVC or 1080p Sony will be a step down in quality from the 11S2
