I just got one of these on eBay, $40 delivered, pretty neat and tidy little unit.
Probably a lot tidier than I would build. good value and a lot less mucking around.

Yep I get that part, I'm in the middle of building a couple for some 1L and 6L Bellco Bioreactors, they only want to turn at 30rpm (Teflon blades the size of your hand) but in the interim I needed a stir plate in a hurry and the above was a good buy.
The ones I'm building have temperature control, timed O2 supply and the stirrer drive, so a bit more complex, designed to propagate enough yeast from 1 Wyeast smack pack up to a 200L pitch
Sort of like this but twice as big - Mark
