whats the big difference between a 20000 dollar projector and a 400 dollar projector is it that noticeable? and also I see a lot of LCD projectors on ebay for under 400 dollars is this for real?? i mean why wouldn't everyone buy that which can project a 100 in screen instead of an expensive lcd tv thats 26 in for the same price???? whats the catch??
Answer
A more expensive projector will get you improved resolution, brightness, contrast, sharpness and color accuracy. Cheaper projectors selling on ebay for $400 are typically business projectors and/or earlier home theater projectors with poor contrast. Addionally, bulb costs on those earlier projectors can be exceedingly high, more than the cost of a new, higher quality projector.
A business projector usually does not make a good home theater projector, for a few reasons:
1. It's designed to be used in a room that's not necessarily dark. This means it will have high brightness, but probably not a lot of contrast. This makes for a washed out picture.
2. It will not have as good quality scaler as a HT projector, since it's meant primarily to use with computers, which dont' need scalers (a scaler, which is built into all modern digital projectors, matches the resolution of the video signal with the native resolution of the projector).
3. They usually have 1024x768 resolution with a 4:3 aspect ratio. For home theater you'd want at least 1280x720 (720p) with a 16:9 aspect ratio to match HD TV.
You can get a decent 720p home theater projector for under $1,000. 1080p projectors can be had for well under $2,000. Do some research online, and don't jump on a cheap projector because it sounds like a good deal. You'll more than likely be sorry.

Answer
I recommend you pick up a copy of Home Theater Magazine May issue, it listed just about every projector in the market. It recommends projectors in the entry level to the high end. Also they have reviews online also on certain projectors. I have been using a Panasonic projector for well over 6 years and never had any problems. Hope this will help you out.
