The original [enamel?] coated grate on my large BGE is kind of deteriorating, and I'm thinking about getting a CI replacement. I'm looking at the Craycort (modular) and Music City (solid) ones. The two tier Ceramic Grillworks one is tempting too...but with each of these "upgrades", the price about doubles, from a low of $39 to a high of $143 delivered. Is the swing rack worth it?
