I am old school because I am first generation, so I like the original crocks. You can also just use a water trap on top of a mason jar or a trap on a food service 5 gallon bucket. The key is anaerobic fermentation, so no air in, only gas out. I made some lids for mason jars for 5 bucks or so to give away. Just a wine trap, grommet, and plastic lid. You can also buy premade mason jar traps.
