To give you an idea on pricing, I'd do around $225 on a 5576, $150 on a P70, and $175 for a clicky FLS that's been converted to USB, so I'm not asking for NIB, but if you HAVE NIB and want me to try to make an offer, no problem. I'd pay for shipping for the KBs, of course. I could also do trades or cash + trades. I've got a bunch of different Alps KBs and dismantled (for bolt mods) IBM Model Ms.
I'm in CONUS, so please keep that in mind.
