I've got 3 Bosch wideband o2 sensors. I'll look up the part numbers and post them, along with the sensor cable length & series (whether they are 4.2 or 4.9). As far as I know they are good. $30 each, can ship for $5 extra. I believe I have mating connectors for most or all of them. I was going to use to integrate with a Spartan controller($80 with a display) to the sbec o2 input for data logging purposes, but life had other plans.
