well, I have the old Autron ones - that are now the Redarc ones
3 x triple gauges
been in for 3 years, never had a problem with them
alarms go off when they reach the set reading
Water, Oil, EGT's, Boost, Batt 1, Batt 2, Amps, and Air Temp
if you are wanting quality, yes it costs
but
as I said, I have never had a problem with mine
