Ebay is the best source especially for single pour and injection molds - any design you want and free s/h.
I agree with SenkoSam. Most of the single pour are used but over the years I fared well with over a hundred picked up. Lure Craft is a source for new molds. The injector molds can also be purchased new and pre-owned off e-bay also. Warning; it can become addictive.[i][/i]
