I found a site today that lists links to a LOT of other sites with PS brushes to download. Many were some that I didn't see listed in any of the threads here so I thought I'd share the wealth!

It's kind of a weird site as far as navigation goes....you have to do a lot of horizontal scrollling and the links to brushes are way over on the right.

Enjoy!
