Well, my wife hit the mark with the 14 gallon Chronical (Brewmaster Edition see link below) from SS Brewtech as my Xmas gift, however I only have an 8 gallon kettle and will need to upgrade to a much larger kettle to maximize the useful ness of this large fermenter. I have a 15.5 gallon Sanke keg at home that I could modify to use as a kettle, however I thought I'd check here first to see if there are any kettles in the 16-20 gallons range for sale.https://www.ssbrewtech.com/collections/chronicle-bme/products/chronical-14-gal-fermenter-brewmaster-edition-1
Those kettles like Shazapple posted are great. Really good price, and the ports are already installed. Keggles look great, but there's a lot of weight to them for cleaning. Cutting the top and punching holes is also a pain.
