Andy, The problem with that board, and the others made like it, is they're very poorly made, and just about everybody that's bought one has had problems with it. The difference between you making do, and somebody else buying those boards, is you're ready, willing and able to actually troubleshoot the problems, and fix them. There are a lot of unsuspecting folks buying these boards, and having nothing but problems with them. And a lot of them have little to no grounding in electronics, and don't know how to troubleshoot and fix these boards. I mentioned also there's a couple of threads on the CNCZone General Electronics forum where some folks have actually gotten these boards to work. Take a glance at those threads and see what they were up against.
