Thanks, Dave. The Salmon gum is a species Ive not found for sale anywhere, so I'll look into buying some from that link (link isn't working on my work computer, but it might be blocked).
I actually have another connection for Gum arabic, but its from Australia. So duties and shipping get pricey. I am trying to see if I can get some of these imports a little cheaper from someone here in the states before looking at international orders. Some are trade restricted as well. That said, given our ongoing trade agreement, we might be able to work our something if you have any species I cant easily get here.
