Thanks for the advice - I did order the antek, so I can compare it to the switcher side-by-side. My main problem is actually with RF interference from the stepper driver feeding back into the controller and confusing it. A couple of caps on the step and direction lines cleaned it up but that's a pretty iffy fix for a production run.
So power ratings might not be an issue at all, but I wouldn't want to have a net loss in available torque. I suppose it would be prudent to check the amount of current it's drawing currently since the prototype machine is binding up and losing steps I could get a good indication of max current.
