1) Gold edge fingers increase the board cost.
I think that depends on the board supplier you use. In these days of the
lead-free religion and surface mount devices, a thin gold plating is a
standard finish for boards, and the shop I've been doing business with
(PCB-pool) offers it as a no-cost option.
That's probably not as thick of strong as the classic gold plated board
fingers, but it may well be good enough for the small number of
insert/remove cycles likely with hobbyist use.

I don't know about you, but I find that I often have to move disks around
