There are a fair number of reviews for this type of projector and the bottom line is that it doesn't really qualify in the world of 'quality'. It is what it is, which basically means that it seems to be barely more than a 'toy'. Does it work? Yes. Does it put an image up on screen? Yes. Will you be happy with it? Depends on you, but generally those who have seen a real projector and these models tend to say 'No'.
You can find a brand new HD projector for $1000. A real 720p HD projector capable of delivering a true 100" diagonal image with top shelf quality for that money. One that includes HDMI inputs, which all projectors really must have these days, as well as a good lens, with zoom, and a contrast ratio that is typically 2,000:1 or greater.
I would steer clear personally.
