Very untrue. AEM's UEGO AFR gauge uses the same Bosch O2 sensor their standalone ECU's use. Even the perceived-as-lowly Prosport uses a Bosch 17025, which is as "wide" as any other wideband and is also used by Motec.
I think Prosports are pretty decent gauges for the money. We've installed quite a few with none having any problems, other then the instructions suck.
I came across a Defi BR gauge last week that was reading 2+ psi high (when often they read 1-2 psi low up here at 4500'). So pricey doesn't always mean accurate... or calibrated.
