Unobtanium - just really hard to get or extremely expensive boards, that most likely I'll never going to get

1. IBM Beamspring.
Spoiler:
2. Alps Plate Spring board.
Spoiler:
3. Lexmark branded IBM model M.
Spoiler:
4. IBM F AT
Want to try - stuff I'm curious about
1. Board with Alps SKFF switches (preferably from Facit typewriter)
2. Brother Buckling Spring (IBM 5576-003, IBM 5576-A01)
3. Tai Hao Fame (Aruz switch)
4. SMK Monterey.
I will consider any offers, but most likely will have to politely refuse you guys across the pond. Shipping costs and customs sucks in most cases.
