I want to purchase one so that I can separate beans from the skins for my son and possibly use it for blackberries and raspberries to remove the seeds. I read you can also use to to remove the skin from baked or steamed apples to make applesauce or tomatoes or potatoes. Has anyone used one? Do you need one with different plates on it? Is there one on Amazon you would recommend? Preferably under $25. Thanks for your help!
