I had OAT as part of a highly experimental flight data recorder, circa 2000, that has now completely failed. I would like to find a cheap OAT gauge (under $50) that I can hook up to my current probe. I want it to be cheap as I will be doing an engine monitor upgrade in the next year which will have OAT on it. Any recommendations for a cheap, temporary OAT gauge?

You could buy the FlightData GT-50 probe individually, for instance thru ACS for $29.85, see https://www.aircraftspruce.com/catalog/inpages/flightdataoat.php
