Adobe Marketplace

Looking for brushes, filters, styles? There is plenty out there but it is often scattered and requires some digging. I have been a growing fan of all the content available on adobe.com's exchange site (http://www.adobe.com/cfusion/exchange/). It is hub for all sorts of user created content and program extensions for Photoshop as well as other CS programs like Dreamweaver, InDesign, and Illustrator. Most of it is free, and it has the benefits of all being searchable in one place. I have also found it is of a bit higher quality since it is moderated by Adobe.

http://www.adobe.com/cfusion/exchange/ is the base page, from there you can select your product, then search by the category your interested in.
