I have a high school friend who is a regional rep for them.  I have had food from his grill at a sampling thing he hosted at a couple of events.  The tri tip was awesome, the rest (chicken, sausage, and some other beef cuts) was good.  He offered me a discount on one, but I have too many grills and smokers already to justify another one, even with a discount.
They are easy is what I recall from watching him.  I believe the company is local, maybe Georgia based?
