I have bought it, but for now I don't use it. The development is amazing but I have a lot of problem with obj import from moi. It depend by the smooth applied by 3dCoat that seem to have some difficult with long polygon (Andrew reply me in this thread http://3dbrush.kriska.hvosting.net/forum/index.php?showtopic=921&st=0&p=3243&#entry3243).
Probably it is a problem with this type of "strange" boolean but I try importing the same in a demo of Zbrush and it work fine.
Anyway with other mesh it's very nice and every day there are some new features!

Ciao
