I built a couple extra stir plates for the guys in the club and I have one left. It is the basic 24V fan with magnet attached setup installed in a radio shack project box. Comes complete with switch and potentiometer. Works best with the 1" stir bar (flask and stir bar not inlcuded). $35 gets it to your door.
