GREGM; I think it's commendable that you are brave enough to launch into designing and ordering your own PCB's from OSH Park. Hopefully they will work as you envision. I just received 2 orders of boards from OSH Park using grj's Gerber files which he kindly provided, and they look great. Kudos to grj for all the research and design work! My first impression of the boards is how small they are. Yikes! I know they are going to be fiddely to build, but hopefully I am up to it. Time will tell I guess. I expect it will be one of those things where just as you finish the last one, you find the best way to do it.
