DC Motor speed controller

[sportsimages]

Help I am in need of a easy to use economical (cheap) device to use with a dc motor pulling under 12a I am using a 12 volt battery and currently use a wiper motor in the device. I need to be able to slow the motor down by slight increments. The contoller will be used in a toy so it needs to be easy to adjust. I am a photographer by trade so please respond in terms I can understand. Specific links or item names and numbers will be greatly appreciated.

Thanks in advance.

Doug

Polyspede has a small, inexpensive DC input speed controller for DC motors. Their web site is polyspede.com but the DC drive is not on the page yet. You'll have to call them.
