Ooops, I guess I do know something else. Mix your own argyro (silver oxide
from Artcraft) for less than a quarter of the cost. The formula is on
Mike Ware's web page.
And for the really chemically enabled, make your own silver oxide for even
less. I was actually poised to do so (mixing up sodium hydroxide with
silver nitrate and right thinking, as I recall) when, um life
intervened...
