O2 sensors.. brand and quality

Just out of curiosity, why are Porsche Bosch O2 sensors so damned expensive?

Will any 3 wire O2 sensor work? If so, are there different applications for each (heat, range, etc.)

What is the difference between a $20 3-wire O2 sensor and $175 Porsche 3-wire sensor?

I ask because I am pretty sure mine has gone bye bye, and I plan on replacing it with the addition of the heatshield most folks add for the LM-1 type sensors. I don't want to overheat this one either.
