    DC motors can be obtained for toys and stuff but they wont be rated to 12V , max may be 9v. Also they wont have a high torque (mostly high rpm type used and are without gearbox or have one outside). Though you can do some PWM control to decrease speed and increase motors torque, or develop some mechanism to do so.
