PlaceMakers carry a wide range of Gasmate and Masport BBQ's.

Additionally a wide range of useful accessories are available - like rotisseries, side burners for boiling or stir frying, a cabinet or shelves for storage - and a weather-resistant cover is always a good idea. 

A hood costs a little more but adds the benefit of being able to rotisserie and roast - plus it keeps your food warm too. And if you frequently entertain a large number of guests, larger is obviously better - consider a 6-burner model.
