I like the black rubber belts like Lehmans carries. We have a lot of horse and buggy people around us and I can get the belts from their stores for less than $5. Shetlers Wholesale carries them also but I don't have a recent catalog to quote the price, probably cheaper than Lehmans though. I have not had problems w/them stretching any more than a leather one will at first. I still like the leather too, but these are easier to come by for me.
