Hi Peter,
The Open DMX has stability problems and the fading is jolty sometimes. Something to do with not being able to store an entire DMX frame at the same time I think. I read an article a while ago that explained the exact differences, but I can't seem to find it again.
actually, the Open DMX is just a standard FTDI-based USB to serial adapter with the outputs wired into a 5-pin DMX plug. in other words, you could achieve exactly the same with a standard serial port, wiring up the RX/TX lines into the right pins. this is all the Open DMX is on the inside. the system driver takes care of the timing, and doesn't do a very good job of it at all.
definitely go with the Pro.
