I notice that nobody ever seems to mention the Pressure Pro system. We bought ours back in 2008, have transferred it between 4 new fivers, and am still using it to this day. Did replace the sensors once, since they were going on 8 years old (still working). The old display is a bit clunky, but it works for us. PP does have a new system that uses your smart phone for the display, but haven't gone there.....yet. Anyway, Pressure Pro for us.
