One man's high end is another man's low end in this audio/video game, projectors can eat up a budget real quick so you need to shop around in that department for a good deal. Spend some time at the avs forum reading and asking as much as you can about projectors. Things are, and will continue to change so fast in the video world that what you buy today could be outdated very soon, this computer I am typing on was state of the art just three years ago, a lot can change in a short time. With HDTV, HighDef. DVD comming in the future and who knows what on all the interface types for these products. That being said, you need to stay up and even ahead of the curve on what ever type of video you go with, projector/RPTV/Plasma or any of the other new kids on the block. The audio part of the system is not as great a risk to become outdated, most of the new audio modes are bells and whistle types of add on anyway. If your handy with tools and understand how to set up a two channel system, then with a lot of reading, thought, and care you will have a great sound system, the internet is a wealth of info. and a great place to buy used audio gear. You should do very well for $18,000 if you put the time and effort into it. I have had just such a project going on for about a year now ( I am slow ) and it's been fun and very rewarding.
