I went ahead and got the M12S and it is a really nice radio. I went from DX4R to this and what a change! This is so much faster and the connection on the track is unreal. The only beef is the cost of rx's. I am buying from all over the world to get good prices. Usually $65-75 new/shipped. I really would cry if I had to go back to my old radio, the new one is that good.
