I am looking at Caprine Supply for pails, filters, etc. and my husband is wondering if there are any less expensive substitutes for what they sell. Like can we just go buy some stainless steel pails somewhere else or is there something special about the pails they sell. How about the strainer? And the filters? I'm not looking to skimp, but if there is a less pricey way to go, I'd love to hear it. Thanks.
