SLA7062M Group Purchase - thinking about making a stepper driver?

There are a number of us on the Electronics_101 group that are getting
together to make a group purchase of the SLA7062M chips for making our
own unipolar stepper driver. The chips cost about $8.50 each, we hope
to get better pricing if we can garner more purchasing power.

If you are thinking about making your own stepper driver with roughly
the following capabilities, please jump over to that group and join in
on the thread.
