Shaun,
The single fastest way to obtain a part # is to call the dealer. 
Either local or mail order. I like Hendrick - 800.476.8322 or Pacific BMW 
800.909.7278 for mail order and refence price quotes.

Seams high. I remember paying $65 for OE 4-wire Bosch that went into my 
E30.

I've never heard an 02 sensor stopping people from driving their cars.
It may through a check engine light. Ignore it. Unplug it altogether if in 
doubt. The engine will default to rich running and lower your milage, but 
that's as bad is it gets.

They are probably wrong. 
All BMW 02 sensors run in the 0-1 Volt range depending on the amount of 
oxygen in the exhaust. 4-wire sensors are heated, that's all. No magic.

Have you tried the dealer?
