We are starting the search for a natural gas grill. Our local Lowe's can order many designs that take natural gas. Before you try to talk me out of NG in favor of propane....our natural gas is free so we want to take advantage of it. the grill will be permanently connected to our line so therefore it will not be brought in for the winter. We plan on putting it under the porch roofin a convenient location. In preliminary searching I noticed that some grills have stainless steel grills themselves and others are cast iron. Now I love my cast iron, but wouldn't it be subject to rust over the winter? I am starting to think that stainless would be a better investment re: cleaning, etc. Oh, and while we're at it, some of those grills are big honking things and I am wanting something a bit smaller, 'cause I'm not that tall. Any models you like particularly? (I already have a charcoal smoker and won't be ditching it) What's your opinion?
