One 5% silver sodder canister (28 sticks, I believe) was $57 and change last week. I've never understood the purity thing of the 15%, as if that makes you better at brazing. I've never once had a problem with 5%.

I'm good with it.

I use 6% on normal everyday copper brazing. If I have to braze to brass or to large (1 1/4" or larger) compressor joints i will use 15%. If I can't get that to flow then clean the joint, flux, and 45%.

Yep, it sure is expensive these days. And I only use 45% if I absolutely have to.
