I've been looking at some of the various etchants (as I'm going to be
making some PC boards), but am confused. From what I've read, Ferric
Chloride is truly nasty stuff, and I'd be likely unable to dispose of
it. It does, of course, have the advantage of being available at the
Radio Shack a stone's throw from my house.

I'm basically looking for something that is fairly easy to use (not
too much mixing, like some of the homemade etchants I found), safe to
people and property (no staining!), and easy to dispose of.

I've seen some discussion of Sodium Persulphate and Ammonium
Persulphate, but people seem to have mixed feelings regarding their
effectiveness. Anyone have any experiences / reccomendations they'd
like to share?
