Where can I buy a replacement video cable for my Gateway monitor?

Seems that, like many other things, monitors today are considered a "throw
away", for the most part, when anything goes wrong with them.

The plug on my cable was cut off by vandals.

None of the shops around will even talk to me about putting a new plug on
the cable.  Gateway won't talk to me about getting a cable.  They don't make
the monitor, but did pass me to the mfr.  The mfr won't talk to me about a
new cable.  Gateway authorized repair centers won't talk to me about the
problem.

Well, I opened the monitor case up and unplugged the cable and got it out
easily.  Now, all I need is a replacement cable with plug with plugs on both
ends.  So, any ideas where I might find one?
