Universal O2 Sensors?

Are they truly universal? The outputs are all the same I think, are the heater circuit current draws all the same? The heater circuit is controlled by the ECU, I don'w want to draw more current then the OEM sensor.

There are two on my car, it's close to $200 for my VW, and the cheap universal four wire sensors are about $20 on Amazon...

I can do some soldering or crimping at that price.
