I'm buying a bunch of homebrew stuff off of craigslist, and the kettle the guy is selling is only 5 gallons. I'm planning to upgrade it, but I can't decide what to buy. I'm planning to do BIAB right off the bat but I'm unsure if my glass electric stovetop can handle it. Should I get say an 8 gallon pot and do smaller batches on my stove? Or should I get a larger kettle and a propane burner and do 5 gallon batches outside? If I do that, specifically which kettle should I get? I'd love to keep the kettle under $100, especially if I end up buying a burner too.
