I'm a CF and poop smith
personally i would buy only a profesionaly made wideband, a diy one already cost like 400-600 bucks. a motec unit (which has been race tested) cost like 1200 bucks. your gonna have to decide for yourself if saving 600 bucks for a diy one is worth your 2-5k engine.
good luck
good luck

No, you aren't talking about the same thing.
The stock O2 sensor (and all replacements for it) are narrow-band sensors, that are only accurate at 14.7:1. These are totally worthless for tuning, but it can be useful to see when you are closed loop, etc.
A wideband sensor setup includes a different sensor and an electronic control box to control the sensor and produce a useful output. These cost a lot more, but they are accurate over a much wider range of mixtures, and can thus be used for tuning. Unless you have specifically reasearched and purchased a wideband sensor system, you don't have one.
I generally think it is worth spending money to get good instrumentation, but the DIY wideband seems trustworthy to me, so I did not feel the need to spend more. FJO and EFI Systems both make professional systems at a reasonable price point if you don't trust the DIY setup. The DIY setup can also be purchased pre-assembled from http://www.techedge.com.au/. They even have some newer versions (1.5 and 2.0) that are more advanced than the DIY circuit.

People have reported that the DIY wideband reads with in + or - one or two-tenths of a "professional" wideband. And that's good enough for what I'm using it for.
