I would have to see the SM out preform my cake pan. I've already seared steak and it works great. The pan looks great and I've used it quite a few times now so I think it will have a pretty good life span for $4 bucks. And when it dies I'll break down and get a new one. Just think , If I only get 4 months out of it the cost will be $12 a year...
As for Fire Butler it looks to be built really well. When I have the money to spend I will most likely go that direction. Maybe get a second Kettle just for it.
