It will be hard for you to find a better keyboard than the Filco, especially with MX switches. I have a KMAC and a Phantom (unassembled as of yet), and I really still prefer my Filcos. I have 5 of them. 3 with reds, an ergo clears, and a browns. I can use them all equally well and I like all those switch types.
If you really want a KMAC or Phantom (or Cheat, etc.), you can get one if you are patient, persistent, and have money to spend.
Good luck with your search!
