As I collect the parts for my system I thought I'd pass along a couple tips on acquiring components at a lower cost.
I first checked a suggested Brewers' supply site for a low cost tank. However, they were out of stock. Ebay had some nice drums but shipping was prohibitive.
I then checked Craigslist and searched on the term "drum". In the NY/NJ/CT area there are several people who sell a diverse array of tanks, barrels, totes and drums. The prices are much less expansive than other online options, including Stenner.
I settled on an HDPE, 20 gallon drum used for Ginger Ale concentrate. Cost was $25.
Connecting nuts, ferrules, tubes etc:
I also purchased a Stenner pump on Craigslist and needed the ferrules and connecting nuts. The prices are a bit expensive and the shipping is typically outrageous. After some research I found a site, Farmboy AG, where the prices are very reasonable, items are sold individually (as opposed to 10 or 20 packs) and they agreed to ship via USPS for $3.00. This saved me quite a bit. http://www.farmerboyag.com/pc_combin...eyword=stenner
Purchased PE tubing at Home Depot. Twenty feet of 3/8" cost a bit over $3.
