What Stand Mixer Does Milk Street Use

I have been watching so many cooking shows recently and notice a stand mixer that looks amazing but cannot find it on a simple search on my browser…. It is grey in color and the mixer is able to make continual increases in speed. It has a long arm and lifts from the front of the head of the mixer. It appears to be a 7+quart? Bowl but seems to work much better than my old mixer. I am ready to invest in a new one but not sure where I could find this or if it is too big for my every day uses. I use my mixer for all kinds of batters, doughs and breads. Help! I am hoping to find one to keep as many years as this one has lasted…
