Sunpro all the way
Inexpensive and time-tested, these guys have been around for a long time & know their stuff. They make 2" gagues for everything.
Autometer is good as well. Accurate, a bit pricier though.
As far as Faze gauges, I don't know, they are the new kids, and they will need to prove themselves.
Pivot and blitz make decent gauges in japan, there are probably many others, but I'm just not familiar with japanese products in this regard.
I currently have an axas shift indicator on order, I'll be converting it to a lift gague/shift light, it will go into a pillar pod under my Air/Fuel gague. I'll be following the docs by an impreza owner, and adding a buzzer at about 500 RPM before the redline, so I know when I'm topping out & it's time to shift, I can also use it to improve fuel economy, by shifting on the first (green) light. I should be cool, so I'll be sure to post pics when I'm done.
