I love the look of the Apexi and the Defi link guages but they are a good chunk of change. That being the case, i more than likely will end up with the Defi D-Guage. The D-guage is cheaper and looks nice. I would get the Greddy but they don't come in PSI:( I just don't see the point of converting to PSI when everything is referred to in PSI.
So your PSI gauges of choice are: -Autometer -Defi -Apexi
