MOTM

Sorry for the double posting.  Apparently, yahoogroups temporarily
stopped sending me email.

I know that less voltage offset is a good thing.  I was wondering if
that increase in performance was at the expense of other
specifications.  In retrospect, it was probably a stupid question.

Mouser has both the polystyrene caps and the nylon hardware (although
the brand seems to be Eagle not Keystone).  Digikey sells the nuts
and screws in quantities of 100, which is way more than I need.  I
had been avoiding Mouser because their site doesn't work well with
Firefox on OS X.   However, it seems to work well with Safari.
Overall, Mouser seems to have lower prices on hardware -- jacks,
switches, etc. -- than Digikey.

While I'm typing, does anyone know a vendor that sells 4-conductor
18AWG cable by the foot??

Thanks to everyone who responded.
