I learned how to cook some great 'q on my chargriller. I did a few mods and was able to hold the heat. The only reason I upgraded was to cook more quantity for parties and to eventually try cooking all four meats for comps.
If you don't have a need to cook large quantities, just do a google search for chargriller mods and you'll be good to go.
