I put in a lot of research before purchasing a brand of gauges and finally went with the Prosport Evo series. Purchased 3 (boost, oil temp (not yet hooked up) and Wideband AFR). All pretty simple to install. Quality is pretty good. Some people complain about brightness (too dim in sun, too bright at night), but I have been fine with the brightness in all cases. Cant attest for long term reliability yet but so far, I would definitely recommend these for the price.
