Well, since we're talking about do-it-yourself rather than plug-n-play,
what about page 20 of the same catalog, Cat #DCM-142, 2200 RPM @ 12VDC
at 2.8 amps, through a suitable gear reduction of your own design?

At that power consumption, I'm guessing it would have LOTS of torque,
especially with a gear reduction in the range of 1000:1 to 2200:1 for
rotator duty.  ($9.50 per motor)
