Sandy,

Thanks, as always for the comments! I'll get busy checking out
some of the sources you mentioned. I'm also glad to know about
that method of adding the Na2- might be worth learning about up
front! I hadn't heard of the Artcraft company- I'll check it
out. I was thinking that maybe a supplier who doesn't sell
exclusively for a specialty market might have cheaper prices,
at least for the more expensive materials. Maybe not, though!
