I got this 1000 gallon tub for only $379 plus tax at the local feed store. They vary in the price depending on where you get it from. Some distributors online that is closer to the factory have it listed as low as $250. If the local feed store is a distributor, they can order it for you. It comes in smaller sizes also. The plastic is decent thickness but not as thick as the rubbermaid tubs. You can look into this company. http://www.behlencountry.com/index.aspx?ascxid=behlenCatalogProduct&i=561
Thanks twilight zone, I may consider that tub if there's one in my area. I've found a local feed store but their asking way too much for a 300 gallon...$450 + tax.
