This is an excellent, robust system! It took me a bit of time to learn the ins and outs, but the manual was a massive help, and I concede that I am a slower, more methodical learner, so that also surely played a part.  The amount of uses and simplicity in adding more states once you learn the how best to use the system in your project is very rewarding and very appreciated! :D Highly recommended and absolutely worth the price!
