Did a little hunting today, and found a site that sells the honing compounds for a cheaper price. Is it as good as Lee Valleys.. I couldn't tell you. Here's the link:

Honing Compound

They sell the Black, Green, and Pink honing compound, but all we'll use for Bussekin knives is the Black and Green. I'm actually kinda glad I found the site, as I'm getting low on the Black, which is a slightly more abrasive grit than the Green.

They sell Stropping Bats on the site as well, but the actual stropping surface on theirs is smaller than the one available from Lee Valley, plus theirs is a bit more expensive.
