If you're looking for the standard, no licence sort, Pails for Scales in Ballarat have heaps for $25. I've got some and they're healthy little things! They freight as well, if you're ages away.
Good Luck
Sorry for posting in here, but I found one of the little critters in my shed the other day (I was quite excited about it actually hehe) Looks like he'd tangled with something and had re-grown most of the tail. Good luck in finding a breeder
