I got the UEGO 1000 which includes the wideband sensor, got it for about the same price as BlueStreak.
The O2 sensor alone, costs around $80.
Does the wideband have to go in front of the cats or can it go in the rear O2 bung? I guess in my case (with gutted cats), it probably wouldn't really matter.
