Summary: I was a little disappointed that the grill box was not stainless (not mentioned anywhere) but in general I would say it's a good grill. If you're looking for all stainless, go with Crown Verity.
Summary: After much research I was enamored with this grill. But reality set in and there were a few things that could be improved upon. The rotisserie heating element is not large enough for the grill and is not easy to light. I have resorted to a lighter. The motor and shaft are sturdy enough to roast large cuts of meat. The smoke box has a learning curve and the sear station is nothing more than an extra burner not the infra red I had expected.
Summary: The Summit S-620 is their "cheapest" top of the line chassis. This grill does not include the smoker box and hidaway rotisserie that the S-650/670 have nor does it have the sear burner that the S-670 has. However, the add-on rotisserie is $100 from Weber and you really don't need a "sear burner". Just preheat the grill properly and it'll do the trick. For starters, this grill gets hot!
Summary: We are new to using a gas grill. Die-hard charcoal users but not so much any more. Assembly was easy. Just follow the picture instructions in order. Easy to set up for use and convenience can't be beat. Now we are cooking almost every night on it, because we don't have to wait hours for the fire to be just right. This grill is attractive, has a large cooking surface and portable with the heavy duty casters.
