What is the best approach for the individuals who do not have variable speed driver motor to regulate the rpms?
The full on, full off deal is killing me.

You can purchase one of the 3 or 5 step pulleys like they use on a drill press. If you do that you may also want to consider using an idler pulley that you can adjust back and forth to tighten the belt. That way seems less expensive too but it has the draw back of a little inconvenience in adjustment while testing your circuit.
