Hey Rick,
I actually went looking for some of these just recently. I didn't find anything at Jameco, unless it was listed under an equivalent product code, but they had plenty at digikey, and since I also needed another PEC pot, I just got a bunch along with the pot. I think in quantities of 10, they are 4.8 cents each at digikey. I haven't received them yet, but probably this coming week.
HTH,
Jim
