I love those tutorials... I’ll be keeping an eye on that upcoming KickStarter they mention. It’d be nice to have a good book of them on my shelf!
I don’t know of any ”black market” Brute & Babe downloads and don’t advocate them if that’s what you were asking about... but it looks like you can get a digital collection from Bart Sears for $19.95!
