The gauge master unit was reveiwed by Nigel Burkin in the Jan BRM so if you want an unbiased veiw I would recomened this reveiw. As I have an older Prodigy unit that I like, it has a knob that can be bi-directional, the others are mainly buttons only, lenz and digitrax, which I found difficult to use when I tried them.
