Looking for EDM wire

Hi all,

I'm trying to get my ducts lined up for a plunge EDM I'm building from
the new Ben Flemming book.

I'd like to get my hands on a few feet of EDM wire of different sizes
and types to test them out.

It is NOT a wire EDM machine, but I am looking to use EDM wire to poke
small holes in sheet metal and maybe slots if the wire can be used
that way.

Anyone know where I can get a few feet of different types of wire ?

Also, it looks as though there are different hardnesses of wire.
since this would be a plunge unit, hard would be desired.
