who makes a good wideband?

[RETed]

I would never use anything less than a Horiba (or equivalent) personally.

Almost all of the "cheap" widebands out there are designed around the 0-5V lean-burn zirconium UEGO sensor that's prevalent in OEM applications in cars nowadays.
This is what flooded the market recently.
IMNSHO, these are all crap.

A penny costs...a penny.
A Snap-On screwdriver costs a lot more than a penny.
Both can remove or tighten a flat-head screw or bolt.
It depends how much you're willing to spend for the "proper" tools.
