This is my 3rd Weber BBQ since 1991.  The first one was propane and still works fine.  Thec2nd was natural gas and I gave it to my son.  The third one, the current one, is fantastic in every way, except the side burner needs an external flame (match, lighter) in order to ignite.  The push button starter works great on the main burners but will not ignite the side burner.  Out of 10 I will have to give it a rating of 8 because of the side burner non-ignition issue.
