Looking for small DC motors and motor speed controllers

I had a nice source on a very small permanent magnet motor, but they
were discontinued. I'm looking for a small, strong, DC motor, around
2 inches in length, somewhere around 3000 Max RPM, with a good amount
of torque (application more about strength than speed). The motor I
was using was in the 12-24 VDC range.

Also, I'm looking for a motor speed controller. I found a kit for
$16, but would rather get ready-made controller circuit boards, rather
than having to solder parts. Anyone know who makes these? I just
need a circuit board I can wire to a potentiometer, I don't need a
case or anything.

This is for an ongoing product, so I'm looking for a source I can get
a decent amount of inventory from.

Any help would be much appreciated.

Thanks
