Yeah - I suggest that you do NOT spend $4-$5K on the 5700. Your first choice (4800) is a much smarter buy, IMO. Don't get hung up on "specs" ... in a side-by-side comparison, I doubt that you would see more than a very slight difference between the two - certainly not enough of a difference to warrant the higher price of the 5700. I'm not a big fan of DLP technology at this point in time. It simply hasn't been around long enough to prove itself re: long term reliability to warrant investing 4 or 5 grand on it. A model 4800 for around $1500, or better yet, a model X-1 for less than $1K is a far better "gamble" I think.

Another option to consider would be one of the many LCD projectors. They are far more likely to prove reliable, and won't be subject to the "rainbow effects" that trouble many people about DLP technology that uses a spinning color wheel to create the colored images. Take a look at one of the Panasonic or Sony or Sharp LCD projectors. Of course finding a place to look at them in action might prove to be a challenge, but I think it'll be worth the effort.
