Ok, looks like pic related is actually a pretty decent constant current source, provided it isn't dependant on the beta of the NPN or whatever the equivalent is for the FET. But I'm still a little on the fence about what's ideal. I don't really want to buy 9 MOSFETs (because they cost more than the bargain bin BC547s).
