I paid 30$ for a pound from my local air liquide dealer... I had to wait a month for it or something dumb like that but compared to actual silver it seemed like a deal. Have you bought any tubing from aircraft spruce in Brantford? Unfortunately I quit my job as a brazer to pursue something else so I'll be without torches for a month or so until I get my new workshop setup and torches/welder up from the states... but then I'll do up that rack I have bent and I'll likely get a front porteur out of 3/8" done up in the next month or two, depending on busy I am with this steel mill gig I'm on.
