I busted my glass mixing bowl that fit on my Artisan Kitchenaid mixer. I see a good deal for 2 used bowls that fit on the "classic" kitchenaid. Does anyone know if the base is the same size so they will fit? I know the classic is an 8 cup instead of a 9 cup and doesn't have the handle but I hate to spend so much on a new one just for the handle. Thanks!
