A San Jose company[*] used to resell them. They worked fine for me.
Only comment is that the insert/remove lever on the individual disk
carriers in the 3-disk canisters are somewhat flimsy sheet metal.
Prone to bending if inserted carelessly by rugby-player types.  They
bend back though :) and it only happened to one of several 3-disk
units.


[*] strongly recommended by a local BSD user; the company merged with
BSDi, I beleive that group now assembles Wind River FreeBSD systems.
