You won't find a better or larger selection of hilts. A simple way to build what you want through their customizing system. There is a lot of information on their site including some background and history for the hilts. Tons of youtube reviews as well as useful information on working with your system to optimize your experience. If I had a complaint is that I would like to see more external buttons to control some of the most common features. The sound level is one of them. The biggest complaint on the reviews is how loud it is. Otherwise, I love both of mine.
