I loved my old NGK AFX, it was dead on with all the dyno's the car went on with this wideband and was when they were about a year old so the shop's WB didn't have a ton of miles on it.
I actually got a few compliments/comments on how nice it was to have a WB match the dyno so they didn't have to watch outside the car.
NGK has come out with a new wideband as a replacement for the AFX.
It is more compact, reads from 9.0 - 20.1 AFR instead of 9.0-16.0 like the AFX and is supposed to be accurate down to 0.1 AFR.
Ballenger Motorsports has them in stock and has a $10 off coupon through the end of June.
