May aswell get the right one, or one that somone else has used.
A narrow band sensor connects directly to MS, but only tells it if richer or weaker than stoich. A wideband sensor needs its own ECU which then connects to MS and gives the actual air/fuel ratio. Which means you can tune to the AF ratio you want at any point on the map.
There are several different makes on the market. I've got a Tech Edge, and my version was a DIY kit, same idea as MS, if you like building things.
