I'm purchasing my gauges soon. Pricing out the same gauges at Genos puts the DiPricols nearly $140 more than the Isspros (Boost/EGT/Fuel Pressure/transmission temp) ($361 Isspro vs. $500 DiPricol). I know the Dipricols use LED but why such a large difference? Should I expect better performance, longevity, something? I've read about the problems with DiPricols and their lighting, but I can't really find anything negative about the Isspros.
