Julie,
I shoot RAW too, but once I've done my RAW processing and saved to 16 bit .tif files, I have the whole gamut of plug-ins at my disposal. Hmmmm. Maybe that isn't such a great thing

Anyway, I usually stick to PhotoKit Sharpener and ICorrect as my "normal" adjustment plug-ins but the Alien Skin film effects are very cool. Whether they're worth investing $199 remains to be seen as the free trial winds down.
Sometimes having a production chain is a good thing. When I'm processing 200 images, I don't have the time to mess with micro-adjustments.
Jim
