There's a guy online selling some used magnetic stirrers. They're $15 for somewhat-beat-up, or $30 for nice-looking.
Anyone interested in going in on some with me to save shipping?

Magnetic Stirrers

1) They make for a healthier, more-active yeast culture. I recall back in bio class, we always used them when growing yeast.
2) They look cool. You get to smugly tell people, "oh, yes, that's part of my yeast lab equipment."
I figure I'll get one of the less-nice-looking ones, provided shipping isn't too high. (As an example, the one on the left in this picture.)
