What is a cheap but good salad spinner to buy?

I have been doing some research on how to preserve my greens and veggies and have heard that salad spinners can help keep leafy greens fresh and crisp. What are some good but affordable salad spinners to consider? My price range would be anywhere from $10 to $15. I would appreciate any suggestions that might go lower than my price range as well as a recommendation with user friendly features. Thanks!
