I found everything except for the Potato Starch, Xantham Gum and Sweet Rice Flour in bulk at Winco for a reasonable price. I've yet to locate the Sweet Rice Flour. I found White Rice Flour, but my bread didn't taste quite right. I found the Potato Starch at Whole Foods in the Bob's Red Mill Brand, and also the Xantham Gum at Whole Foods in Bob's Red Mill.
I'm currently trying out the Arrowhead Mills Gluten Free All Purpose Baking Mix on banana bread. One of the kids interrupted me and I lost track and put in 1 tsp of baking powder instead of 1/2 tsp. I guess I'll find out pretty soon....
