"I like the droplet feature"
I like Batch File Rename because it is has all the features I want, is really easy to use, but very flexible. Rather than have multiple windows for designating final names, this app does it all in one window, and it has a setting where you can use it as a droplet for doing the same rename task over and over, which is pretty clever. I didn't mind spending the 14 bucks for this app, which is a couple bucks more than the other ones I looked at.
The rename according to text file feature was a little tricky, but I contacted the developer for assistance, and it's real easy to use. At first glance, it threw me off. Other features were very easy to learn, though.
