I recently stumbled (I love stumble upon!) across this Photoshop Brush site that seems fairly new. http://www.brusheezy.com Seems to have some pretty cool photoshop brushes if you're a brush junkie like me and its updated every day! Its kind of addicting!
this is where most people get their brushes http://www.deviantart.com/ that site has good brushes though, there is more of a selection at deviantart though.
the best brush resource I have found (via digg) was the one mentioned above. (http://tutorialblog.org/free-photoshop-brushes/)
Daily??? This is exactly what I need! (one problem: photoshop will be loading slowly for having so many brushes)
