I needed the red mixing bowl to complete my set and finally came across one today at an antique shop. It's not perfect, but I went ahead and paid twelve dollars for it. I think it was a fair price. The blue I found at my neighborhood Goodwill here in Portland, OR for four dollars, and the green I found at a Goodwill in Miami, FL also for four dollars. The yellow belonged to my grandmother, and I had it for a few years before I started collecting Pyrex. My dad let me keep it when we cleaned out her kitchen, along with her vintage kitchen utensils. It's the one bowl that always makes me smile when I use it.
