Lol. No kidding. I used a hole saw and a die grinder. I've made lots of holes in metal metal over the years and I never thought I needed a punch. Must be a homebrewer thing. If you don't buy a Greenlee type of punch and instead buy other tools that will enable you to make holes in metal, you will be able to make many, many other things besides holes. A punch is only good for making holes in thin metal, that's it. Go with the other tools and you will be able to do a lot more stuff.
