If you need less reduction than the stock FP box gives, don't be afraid to try to make a simple gearbox using one or two stages of FP gears.

The gearbox in the white paper I linked was done on a drill press as well. A drill press that is in good shape and some patience is all that is needed. Just start with a small bit (small enough to fit in the punch indentation) and open it up very slowly. I also did the mod to skip the first stage of the gearbox like shown on the HOT (FRC67) bot using just a hand drill and a dremel.
