I use MCP's Web resize and sharpen action on everything I post on the web. I use their High Def Sharpening action on everything I print.
For my color processing, I tend to use
Nichole Van actions. Seriously love, love, love them, but then again, my processing style is to go for a pop of color.
I also use Coffeshop's *free*
Perfect Portrait 2 action on all my portraits. There's a newer version out, but I don't like how it works in PSE.
