Luckily you can thrift them for <$5 pretty commonly. In fact, I have a $2 one sitting on the desk next to me right now. So many high school kids buy them new then leave them sitting around until their parents donate them it's silly. I've probably purchased at least two dozen over the years...for my kids, for their friends, and then quite a few I flipped on Ebay for $50-60.
