I was trying to find some FeCl for etching brass, but with a dozen Radio Shack
stores in this town, none of them had it in stock.   Later I happened to be in
an art supply store (the Dick Blick chain) and found they carried it for about
$4/pint (about half the price I rememeber Radio Shack charging).  In addition
to etching its used for getting a patina on metals, so another source might
be a store that caters to stain glass artists who want that old antique look
on the metal parts of their work.

P.S. - But for PCB work, count my vote for that pretty emerald green CuCl.
