Weber
Owned a couple of cheaper ones, then bought a smaller Weber. Loved it and never had a problem, then gave it to my son when my wife bought a larger stainless steel grill on clearance at a Sears Outlet. Well the new grill had all kinds of consistency issues, so last year we went and bought the Weber Genesis II 410 and absolutely love it.
Their prices are controlled by the manufacturer, so all the major retailers usually have the same price that can't move. Maybe you can negotiate for dents or a floor model, but you don't need to waste time shopping around
