There are also some forums they are starting there which are so-so, but can give you some answers that may not be covered on the site. Lot's of people are asking the exact same questions you are - and they definitely have answers.
Keep in mind that 'regular TV' when you blow it up to 8+ feet diagonal really looks like crud. You will play a DVD, then look at TV and go "This sucks!". You may want to look into cable HDTV or over the air (OTA) HDTV with an antenna and receiver. HD on projectors is simply stunning.
Most of all, if you are thinking of putting a front projection setup into your well lit family room and just 'use it everyday' - forget about it. There are much more satisfying ways to spend your money and you will find that front projection simply does not cut it when there is to much light in a room. Unwatchable.
At $2K you can pick up one of several decent projectors designed for HOME THEATER USE (do not look at business projectors!). The Panasonic AE-700U is stunning for the price. Closer to $1,000 you have the InFocus SP4805 or the Optoma H31. All are very good, but the AE-700 gives you over twice the resolution and a lot of mounting options which the H31 and SP4805 do not.
Lots of choices and things still to consider though.
