You can order them direct from CNC Drive's website.
Gerry, genuine question - I'm in the market for a new motion controller (and I'm not going down the NVEM route again). The UC300ETH looks to be a more capable card than the UC400ETH (which confuses me because "400" is obviously better than "300") in terms of I/O (would I ever need more than a UC300?). I'm pretty certain that there's no performance difference between them, just a functional improvement of the 300 vs 400. Or have I missed something?

Price-wise?, I'll pass on two pints of ale this weekend to make up the difference.
