I pulled the trigger putting the Onyx Visor Card to use and bought the HC kit which fits the large mop bucket and a heater. Kegs cost 30 bucks if you have a pal who will sell you one. The big bucket go for 75 extra. Its only plastic huh? Now I read somewhere else on here a person needs a router to make the hot plate work right. Who knows the scoop on that deal? Thanks. I am also having the plumber build the do it yourself model from copper. Guess I will use the first one which appears. I am an eager beaver to make some hooch..lol.
