Right now, I have the updated versions of my Photoshop brush sets located on my web site. I'll be working on updating the sets on my DA account, as well. I usually update my site before anything else. ( Edit: October 4, 2009 -- New domain. I will post the link when I've added the brush sets again. )

GIMP users: A while back I was asked by someone if they could convert my brushes for use with GIMP and I was okay with this. You can find these conversions on his DA site -- Project-gimpbc DA. Thanks a lot, fence-post!
