It’s also nice to have a cheap, smaller one for doing little amounts of things, like onions. We got a Proctor Silex at Rite Aid for almost nothing, and it’s been great for very small, occasional jobs; it looks like it holds about 2 cups, takes almost no space, and is very easy to pull out and use.
Even though mine is the regular size, it is out 24/7 front and central, which makes it get used a lot even for one onion.
Also shredding. I forgot. Potato pancakes, carrot salad? Done. So easy.
