I am furtunate to be one of "those guys" that before I attempt something I don't know, I spend countless hours reasearching and researching before I do it. I have to say, that out of all the LFS/internet/book reading, I learned the most from everyone here on 3reef. K+ to you John for this post as it re-inforced that I needed to learn before I attempted to build my own. And to say, it has paid off. Not only in time, but in $$$ also by learning from this and many other threads. In conclusion, the key to the right setup is plan, plan, plan.
