Although I prefer PBT keycaps, this doubleshot ABS Alps-mount set looks great on my Northgate Omnikey 101. I have painted the case burgundy red, and I used blank black bottom-row mods and spacebar from Matias to enable this set to work with a winkeyless keyboard.

Great quality, double shot keycaps. Be careful though, the caps lock and Spacebar keys will not fit a Dell AT101W. Fairly big design flaw since the AT101 is one of the more common ALPS boards out there.
