This product used to be free (including the universal version).Maybe you can find it:
It's version 1.1 (NOT 1.1.1).
It is a bummer that has changed. However, this program IS good enough to charge money for. I'd bet more money could be made at a ten dollar price point (this product probably doesn't need a lot of support) because you'd get more buyers.
Anyway, I recommend this product. Put it in your finder toolbar and/or dock. Then drag.
