I want a 2 or 3 burner gas grill with a side burner. I want one that can have a new burner,side burner or regulator replaced basically don't want one with crimped connections. I have a grill we have owned for quite some time the regulator went out and the thing cannot be replaced. so need to trash a good usable grill in every other way. any suggestions on kind and place to buy appreciated. Thanks
