The interface is almost as nice as the pro version (2.X). I'm hoping that will be addressed in the next (2.X) version of Mini, whenever that is available. I'm sure I will eventually want the extra features, but Mini is a great start and does what I need. They offer an upgrade price from Mini to Pro, so that helps spread the cost out as I learn more about the software.
I converted the cost from Euros for purchasing directly from the developer, and the app store is a better deal by a few dollars (at the time I did the conversion).
Overall, I'm very happy with my purchase.
