Valve seat grinder

I'm slowly filling out my hobby shop. I weant valve grinding equipment. I picked up a black and decker valve grinding machine last summer. I'm looking for something to do seats and it seems I can buy the stones and arbor new pretty reasonably. it comes with a piece that looks like it will chuck in a drill to drive the stones.
When I learned how to do this as a teenager we had power head that was specifically built for this.

So i guess my question is can I drive these with a big drill? Or should I keep holding out for a reasonable used setup?
