some msd/o2 sensor experience needed
Aem, lm2 are both really good gauges as long as you get a wideband and not a narrow band one (useless)
Yep, the wideband is the only one to get.
I got this kit on Ebay for about $160 and it works perfect.
Comes with everything but a welder to put the bung in. :D

Over 200 bucks frome jegs, and close to 300 from thier catalog.
Comes with black and white faces both, data logging cable, mounting hardware and all.
It has a few nice additions in it also, like error code display.
One day mine started flashing E9, E9, E9 and I found it meant "Low Voltage" and had a broken alternator field terminal. (not charging)
Another day my car hiccuped and I glanced at the A/F guage and it was WAY lean for a few seconds and then it came back up. (Fuel pump was going) and I caught it before the car died somewhere out on the road.
