You know, in replying to your posts, I looked around at the saws on the web, and I don't think you're going to find a saw much different than the one on the website for the money. Jet and Wilton make saws very much the same for varying prices.
I would stick to one of those for parts availability, and because i think they have a better saw guide system, the heart of good, accurate cuts. If you plan on doing alot of cutting, consider getting a chip blower to help cool the blade and work piece. Liquid coolant systems are great but can be messy and like diesel fuel, micro organisms can grow in the coolant. There are biocides available to control growth, though. Also look into bi-metal blades for extended blade life.
Your next best bet would be to keep an eye out for industrial machine tool auctions. Sometimes there's a deal to be had in a larger, more capable, machine. The smaller saws are like the sub compact tractors. They can do, just not as fast or as much, as a larger saw.
I think for the many projects it sounds as you may have in the works, you may want to up your budget in the future for a bigger saw.
