I have probably 25 SS bowls. My initial set of 5 nesting bowls came from the Lynchburg Company more than 30 years ago. When I started my personal chef business, I bought some others to take with me to the client's house. My husband's mother had a set of three flat bottomed bowls with rings on the side (which are handy) so I have those as well. Now, everything I had for my chef business is home with me now, and many are duplicates, but they have lasted me for years. Got the newer ones at the restaurant supply. When I bought my Cuisinart hand mixer, a Kitchenaid bowl came with it, and that by far is my go to bowl for just about everything. I even use one of my MIL's flat bottomed ones for my salad bowl.
