Peter Quint videos are great tutorials, that's right and it's FREE !

If you have money to invest into, cmiVFX have goods tutorials too, except the 4 last Houdini Tips by Varomix. Personally, i think this guy don't know what he does (e.g. Vol4, 200 channels CHOPs for drive 1 scale…)

Since we're on sidefx.com, ill vote for tutorials here!
But i'll have to agree with the majority, his are great.

eitht.

Great video tutorials that break learning Houdini up into modules on a specific subject so you can pick and choose what you want to learn. Plus great tips and tricks videos.
