12VDC PM type motor help

[click62]

I am in need of 3 - 12V DC,permanent magnet type,2 pole/4 wire motors and im having one heck of a difficult time finding them. I need this type because i will be interfacing these motors with circuity (probably a solid state relay IC) and i will need to reverse the direction through programming(using a microcontroller). My question is, does any one know where i can get these motors for a relatively good price? Also, is it possible to use a field winding type DC motor and interface it with some sort of circuitry that would be able to switch the polarity of the power going to the motors through software?

Thank You to all who reply

You may find such low voltage motors and drive electronics from following leading motor producer's sites: Faulhaber (former Minimotor), Maxon or Pittman.
