they have a 320 page catalog with everything in plastic you can ever think of. Once your in their catalog find the search; type in, Inductor Cone Bulk Storage Tanks. As Posted above on the conical fermenter the usplastic.com has conicals example; 15 gallon 19"x21" base 60 degrees angle for $68.97, metal stand for $67.01. The 30 gallon $85.89 stand $71.10. These are made of medium density polyethylene meets FDA standards max temp 120*F. Tanks are translucent for level U.V. inhibitors. All tanks have a 12" screw on lids with a 2" threaded outlet. Another model of tank holds 18 gallons good to 140*F 17"x 23"x 52 degree taper 2" threaded outlet for $175. I believe this is a heavy duty model. They even have March pumps besides every valve and tubing you can think of including Tygon product tubing rated to 275*F. Just a heads up what your missing or not knowing what is available besides the high dollar LHBS that you think is your only source of brewing supplies. Many LHBS places buy from these companies then add their extra profit with you thinking they are the only source of this product or it was made exclusively for them.
Just a heads up on what is out there.
