Gene,
This probably isn't exactly the one you're looking for, but
it's considerably cheaper than $90. You do have to install a 5k
pot. They work very similar to the mini-lathe motor controllers in
that you have to ramp up the speed. I think they're based on the
controls for treadmills and are rated for 8 amp continuos output at
130 VDC. I've got two of these fellas I'll be using on my CNC saw beveler.
