I have 3 FilcoTKL's, 2 blues and one brown with ninja key caps. They started to get quite expensive for what they were.
I use an IBM model M today with a Model H controller replacement.

I also have the Filco keycap puller. Keyboard cleaned and saved!
I now use a Keychron K2 with browns. My fingers are getting too old to use blues on a regular basis.
