Del-Mart or Bob's makes senkos almost identacle to yamamoto. I got 2 Del Stick molds that I've been using for a while, and you can't pour a bad lure with 'em! As far as saving money, in the long run you can probably save some money, but you will spend alot of money on all the molds, colors, glitter, salt, additives and such when first starting up. I've been pouring for only about 3 months now, and I know I have spent ALOT of money. But its a great hobby to have.
These were poured in a Del senko mold.
