Does it have to be wind-up?  I just picked up a BBQ rotisserie
motor at Princess Auto (http://www.princessauto.com) for $9.95
Canadian.  It's small, self-contained, runs at approximately 1 RPM
and is powered by two D-cells.  Enough torque to spin a piglet
(mmmm!).

I'm planning on using it to build a barn-door mount.  I'll build
it a bit longer than necessary, see how fast the motor spins
under load, and then decrease the tangent length to get the
correct rate.  Cheers!
