Brown cherries are always a good bet. Keep in mind they don't click like the blues, but damn they feel like buttah.
datacal has Cherry-made G80-3000 boards with brown switches. There are a few differences between the G80 and the Filco though:
Cherry uses PCB mounted switches, Filco uses metal plate mounted switches. Metal plates are not "better" by nature, but many prefer the solid feel and weight. I like both. IMHO metal plates mount is best for linear / tactile switches (Black, Brown, Red) and PCB mount is better for Clicking switches (Blue).
There are also some crazies out there tellin' folks that Cherry saves its "best" switches for its own keyboards. I'd like to see some sources on this.
Also, filco uses ABS keycaps, Cherry uses PBT which has the advantage of hardness, durability, and wear-resistance. They keycaps on Cherry boards have a REAL advantage over the Filco. Then again, you can get high-quality replacement keys for the Filco in a snap.
In conclusion, buy an IBM Model M or Unicomp Spacesaver. They're just awesome.
