I think they introduced the Master Touch model around 1990 but then discontinued it in the states for quite a while until again recently. It includes the baskets, an upper rack, different wheels, and a silicone type grip on the top damper so it doesn’t burn you when you adjust it. It’s also a little taller than standard kettles which I find to be a nice touch. I might be missing something(s).
Weber kettles were hard to find around here right before Memorial Day weekend so I went to several retailers. Some only had the various colors and I wanted the classic Black. Eventually found Black ones but only in the Master Touch model which was more costly. I thought the upcharge was worth it to get the accessories and the color I wanted.
I had actually read about the fire bricks when I was looking into getting the Weber. When I cooked the fatty and all the jalapeños last weekend for a Memorial Day party I basically used a basket like a fire brick by turning it around backwards and using the flat side to contain the unlit charcoal that would be consumed during the cook. Worked great.
Only thing is I also read after the fact that banking the coals right against the side like that is really hard on the porcelain enamel. Especially so if using lump charcoal, which I usually do. By keeping the charcoal off the kettle the baskets/slow n sear supposedly lower surface temp by 200 degrees.
Doesn’t sound like you’ve had any issues though 🤷🏻♂️
