with what would appear to be a plethora of devices using SMA connectors, why
are they still so expensive?

Precision machining. The tolerances are tighter than most connectors.
Some of the newer RF connectors are even worse. They have to be machine
assembled and ordered made to length, or with a single connector.

Regrettably true. The SMA/SMB series are the last ones I know of
that still have big enough individual pieces (barely) to be hand-
assemble capable. Those tiny center pins are a real pain, though...
