Barley is readily available; burns great, and is cheaper right now. This might be a case when bigger isn't always better. Losch and Yellow Flames are the two best Barley machines......hint, hint.
Make a call and get Barley pricing. I'm am in the same mindset as Dave and don't like to see pea in a machine that is designed for rice. Controlling the fire could become an issue, and having 'The Much-I-Do Hose Company' over isn't a fun event........too much paperwork.
