There are so many options with these sytems, you can do something for as little as a few grand and spend $6800 if you try.
A phone conversation will go a long ways towards me getting a better feel for what you want, and what you need, which may be two totally different things. I will be around the shop all weekend working on a project for a magazine How To article, feel free to call 8AM to 5PM eastern time
You can do allacart and get just what you need or a complete package.
