You nailed it. One brand of machine will not overall make your wash any more profitable than the brand of grill used in a restaurant. Look for a distributor you feel comfortable with, and that will show you how to work on your machine. Also ask him about service and parts availability after the sale. Try not to get married to a distributor whom you have to use after the sale, as we all know the success rate of marriages. And good luck with your wash. A little of that never hurt.
