honestly, the E210 is all you need plus the natural gas conversion kit http://www.weber.com/explore/grills/spirit-series/spirit-e-210 This might be overkill but would be what I would get for a natural gas application. You don't have to run all the burners and its not too massive. Hell the grill I have now is a 5 burner commercial series and 90% of the time its just the gf and I as well, I just run 2 burners http://www.weber.com/explore/grills/summit-series/summit-e-420
