I am deciding between the Summit 470 and the 620. They are the same price but for me it comes down to getting a big grill with a sear station or a huge grill without one. Added grilling space is always a plus for me as when I cook on the grill, the whole meal is done on the grill and right now it takes 3 shifts on my smaller grill, but the sear station has me baffled. Call me odd, but I don't eat steaks. I can see the appeal of the sear station for steaks, but what else would I use it for? Do any of you use that station for things other than steaks? I understand the 470 has a smoker box, but I have a WSM, and would just use that. The rotisserie is not really a draw for me, but if I really wanted one, I could buy an add-on for under $100 from Weber later. Right now I can't justify the smaller grill for cooking one steak one every 15 years, but all my buddies swear I need to get it. So if anyone has ideas on other things I could do with the sear station, please let me know.
