I came to the same conclusion after noting that anything over about 16ppr
cost $50+, until I found :

Sure, stepper motors are a little bulky, but the extra mass makes them
feel *awesome* and 100ppr is easily achievable with cheap ( $3 ) surplus
units that panel mount fine and fit 1/4" shaft knobs.

Got my stepper motors from Herbach&Rademan for $2.95.
Really being able to give the old knob a good hard spin and have it zoom off
like an old Tempest controller is nice.  This plus acceleration makes
controlling 15bits of controller data total cake.  And you wont have
to pull a Roland and add any wieght to the unit to make it feel like theres
something inside the box...
