I am using Folia-tec mesh too. You can get it online or at your local speed shop. It is good, but mesh isn't that great anyways. There isn't much of a difference between gutter gaurd and other mesh brands. Folia-tec is just a little thicker. Your best bet would be buying a street scene kit and cutting it to fit. It's expensive, but sturdier. I think it is the same if not very similar to Elky mesh.
