I don't know, but we've (Corpane) have been looking for such an animal for a
while now. We have water cooled machines and would like our on-board
microprocessor to control how much water is let into the system. So a stepper
motor controlled proportional water valve is exactly what we need.

We looked everywhere, I think we found one place that sold it but it was an
outrageous price (somewhere around $1500). If anyone knows where we could
find a cheaper version than that, Please help us out and tell us where.

I guess our next step will be to build it ourselves. But we really aren't set
up for such an enterprise.
