I just got the Faenza icon set for KDE abd I have to say that .... THEY ... ARE ... AWESOME!!! The only thing that I dont like is that my system tray still has those ugly bloated looking icons. They are fuggly uggh.
Anyway, you can get the Faenza icon set in kde-look. I suggest you get it if you don't like Oxygen. (Is's too flossy for me)
