Prices of plugins are relative to functionality and need. $30 for this plugin and some others isn't bad considering the complexity of the features. I didn't think twice about it because I needed, and wanted this kind of feature. Mike is correct in his involvement supporting this plugin, and continues to make improvements. His end goal is flawless operation. He and others have a technical skill that most of us don't possess, so we are glad to have devs like him making nice features available.
