which wideband to get?

I stick by what I've said above... Your WB readout shoudn't be all over the place. I have quite a bit of experience with this it is VERY common knowledge on all of the other 50 forums I visit so I don't know what else to tell you.
Your computer constantly corrects for a rich/lean condition during CL, however, it's doing it so well that your actual A/F ratio should be able to stable itself.
But don't take my word for it... I only tune my car with my laptop myself as well as other SHO's across the country.

Once again your statements are unclear and confusing..
FFFman posted a picture of his WBs with his stock ECU. As you can see from the video. In CL his guage "bouced back and forth"
When you say "I only tune my car with my laptop". Are you referring to a Standalone unit now vs a stock ECU? I am thinking you are. If that is the case. The AFR should be constant because I stated before in my previous post. That SA is does not use the voltage from WB to determine AFR. It uses variables like rpm, coolant temp, and load. It then looks up on the table how much fuel to dump at the point. So it should be constant.
Works just like an old carb but with electronic monitoring of the conditions.

With my laptop, I ma just explaining that I have some experience. I am tuning the stock Ford EEC with a piggyback system hooked up to my laptop. I datalog and make changes via the TwEECer and also datalog my SA WBO2 to the same program. My stock computer uses NBO2's, however, with careful tuning of the both the high and low fuel injector slopes, and injector offset vs battery voltage, the computer is able to keep the WBO2 relatively steady under PT and idle conditions.
Although the WB was not being monitored on this run (I didn't plug it into the serial port), I can monitor both WB and NB at the same time. The NBO2's will switch like crazy (as they should), but the WB will have minor fluctuations hovering around desired LAMBSE (commanded A/F ratio).
I don't think the explanation is unclear, I think many of you are reading into something else and are trying to apply what I'm saying. In addition, NOT ALL stand alone ECU omit the O2's. My Dad's SA replaced the need for NBO2's and uses WBO2's.
I like the zeitronix unit, however the feedback is a bit slow. My main like about the unit is the datalog feature (boost, EGT, TPS, RPM, and Wideband). It's a lot easier to use it for tuning because of the scaling. This is what I use on my supra, but I'm only using piggy back stuff on her right now. So for the bang for the buck you can't beat it.
However on my NSX I use a AEM wideband commander, tied with EMS, and a AEM serial gauge

Trev Im sure you know this but witch setting is ur uego set to? The uego has two settings 0-1v to vew in narrow band and 0-5v for vewing in wide band.
whats the diffrence between the dual channel and single channel uego?
Dual channel has 2 O2 sensors one for each bank on the motor.
depends on cost.
UEGO can be had for cheap but from expereince they dont last very long.
I ate my last one in under 3000 miles. Sensor is around 80$ on ebay.
was running meth and unleaded pump.
If you want cheap then the AEM works great.
Also run the Greddy wideband.... still cant put my finger on what it really means since there is an adjustment based on sensor position and exhaust temps.
anyways, never sure if i get it right.

How much meth were you running? I run a 50/50 mix of meth/water with pump gas and have been running my WBO2 for a few years now (with some road course use). Just curious as I don't want to clog up or burn out my sensors prematurely if I don't have to.
