I have a Model M mini, that I got as NIB. I did the nut/bolt mod on it as 21 of the plastic rivets were broken. Keyboard is in excellent shape and has been used on and off for about 3 months. Still have the box too.
I have two unicomp spacesavers. One black (ps/2) with linux layout and one white(usb) normal layout.
I also have a filco tenkeyless that originally had white Fukkas. I replaced them all with NIB black ALPS and then went ahead and replaced the click leaf and spring with those from the Fukka. I don't know, but think that kind of makes it a complicated white ALPS.
I need to post pics, I know, I know.
Let me know if there is any interest.
Oh yeah, after much thought, I am chucking it all and running with the HHKB.
The small form factor and default keylayout make a win for me.
