I got mine at Goodwill for $20 . . . and you should look on Craigslist if that exists where you are.
If you look regularly, then you can probably find one that is perfect and perfectly priced this way. If you are in a rush, then just do a quick look at Craigslist and the local thrift stores, then buy one new if nothing pops up right away. If I do my due diligence and look, then I don't worry about spending the extra money on new because at least I tried, but it's amazing how often just exactly what I need pops up used. Good luck!
