It's a good use of time to peruse the resources at
www.mimf.com . There are builders, suppliers, newbies, old hands, famous builders, and everything in between. Plus the way the place is set up involves moderators who cull old messages to preserve the material that involves substance from someone who has experience, so if you do research there, you'll find material that's worth reading. It's an excellent place to learn and to get good answers to questions just like yours. It's a nice complement to this site: a different place with a different purpose, but it dovetails well.
