Anyone know how thick the walls are on a keg? There seems to be plenty of people using kegs with banjo burners and without problems. I know keg walls are definitely thinner than a tri-layer pot.
Also, more than you need right now? If you're thinking of getting up to a keggle size eventually you might consider that spending $100 now for a small BK and $100 later for a keggle means that you've spent $200 for a keggle. I think the 10 gallon pot size is an awkward size. If you ever have the urge to brew more than 5 gallons you still don't have a big enough BK. This has been my thought process as I get ready to step up to full boils.
