The cards look nice, but without pricing, it's hard to tell if they're a
good value.

"This flexible device, designed specifically for step motor control,
alerts the user when the motor has lost steps during motion."

I think that speed is mostly useless as well, but the faster the
timebase, the smoother the acceleration profiles can be.

not really bother looking too hard for pricing.
