One very small caveat:
I found the touch of the Filco switches to be too light to my preferences, and they're loud in a way that sound cheap rather than industrious.
I suspect he will have the Fukka variant of that keyboard that EK was selling off. XMs are
not light, and Fukkas are very loud (cf ABS M1, which isn't even clicky).
Why did only the Fukka version have controller issues? I don't know how compatible the different ALPS types are. I certainly want this swap to succeed, as XM sucks, while complicated blue ALPS are a wonderful switch.
