I'm guessing they would be out of my price range but I'd love to have one
for cutting the magazine hole out in my AR-15 lower blanks.

A die sinker EDM can be very useful, but it's a terrible choice for
something like a magwell, i.e. removal of some 4" thickness of a "soft"
material like aluminum. Wire EDM is what is sometimes used instead of
broaching.
