Sidebar regarding the CAC M13 muxes: Everyone I know who uses 'em
loves 'em, and they retain pretty high value on the secondary market,
which suggests that this is not an isolated phenomenon.

Did you like your WideBank 28s?  I am realistic enough to realize that
there are good reasons (spares standardization, etc) to swap out
working hardware that you like in favor of something that is the same
as the rest of your network...
