GIMP has a DDS plugin also that I've used successfully.
It also has batch convert, so I was able to convert all of the DDS texture files to PNG files, so I can browse them on my HDD, which is VERY convenient!
I know this list is a bit out-of-date (as in it's from beta) but figured it may be useful for people as a starter:
