Awesome! Thanks all. I went with the 16 in due to a nice 25% off sale at my LQS.
And then I had rewards points, so woo hoo, it was a steal.
I bought an off brand on Amazon and have never been able to get it to rotate nicely without also shifting my ruler, so that one I am donating to our local craft/thrift store. It works and is fine, just not a joy to use if you will.
Hoping I will like this one better!
