PMD Motion Control boards and Chips?

Hi guys

I get junk mail from this outfit and today and interesting thing
came in about an "economical" motion controller that is for PCs (PCI
bus).

I also noticed they have something similar to what Gecko has been
working on that deals with steppers and stall prevention...

Some of the specs are just out of this world if I am reading them
correctly - 5 million steps per second! Useless for steppers I think
but interesting for servos I would suspect.

Has anyone used any of their products? Any idea of what the costs
are and such?

Thanks

Chris
