did kabobs on one of those this past weekend..awesome bbq..that being said, i'd get the SWG. the money you save on chemicals will soon pay for the bbq and allow you more leisure time to cook with the simplicity of the SWG once you get it setup. zeobrite is only about 85 dollars for 100 lb (equivalent to 200 lb of sand for filteration)..not really expensive when you consider how long it will last you.
