I have exactly the same problem as other reviewers - despite cleaning and seasoning the grills for my Baron 590 they are rusting out. Looking for a source for replacements I nearly fell over when I saw the price. I bought a Broil King so I wouldn't have to replace my bbq every few years but for the price of the grills I maybe should have stuck with my old strategy of buying a new cheap bbq every few years. So disappointing when you make the conscious decision to buy what you expect to be a quality product.
