I got wise and connected a 40mm 12V fan. It spins but wont switch off, it will vary speed a little but not much.

I feel I've done a similar thing with my fan controller on my brand new Pbot Jr. The fan I was mounting was working perfectly, but I managed to short the fan leads (doh) and now it will only run full speed.
Thing is, to ship that 44c FET from Digikey to Australia costs $34! Ouch.
Would anybody know of an alternate source for these that aren't so pricey? Thanks.
