RAW converter

Can anyone recommend a good free converter for raw files? I need to view, adjust and convert a bunch of photos.

Downloaded one and the quality is appalling.

gimp with a RAW plugin?

I can't personally recommend it as I use Photoshop for all my image needs, but it might work.

Canon cameras come with DPP, a good RAW converter. I don't know if Nikon cameras do or not. ufraw is something that popped into my head but not sure what it is. I use CS4.

What cameras do you have?
