I may try a KFLOP. Price isn't bad, but its still USB based. The TCP/IP controllers, like Galil are pricey. I think if Mach did away with PP support to where an external motion controller was needed, we'd see more lower priced options out there. Right now, the PP does a pretty good job for a next to nothing cost so for most people, there is no real need for anything better. If every Mach user HAD to buy a motion controller board, we'd see more competition in that market. I'm really surprised Gecko hasn't come out with anything viable, although I know they are working on something.
