Should I choose a grill with a side burner?

A side burner, while unnecessary for grilling's sake, can be an invaluable tool to save you a trip to your indoor kitchen. Ideal for cooking a side dish or reducing a sauce without leaving your grill unattended, a side burner exists purely for convenience sake. Since side burners draw from your fuel source, propane gas grillers may find that this add-on depletes their tank unnecessarily.
