Dear Missy,
Hi!
I haven't ordered from PMC supply, but I have bought metal clay and other related items from Rio Grande, Wholle Lotta Whimsy, Pam East at Pinzart and Metalclay/silver clay before, you may wish to spend a little time comparison shopping this afternoon, all have reasonably good prices. I bought many of my enamels from Pam, she's lovely and very helpful, I saw her make enamel beads at last year's Bead and Button. I buy other tools and metals at Rio,so which one I go to depends upon what other things I need when I make an order:

Hope this helps,
Love, Jan [:)]
