Geiger,

That sounds very high.  I bought my new O2 sensor from The BMW Store
for just about $90 with shipping.  Rodd Sidney will sell ya it for
even less (you may need to reuse your old connector, though).
The factory sensor came with a plastic cap over the sensor end to 
protect it in shippment and had the anti-seize compound on the threads.

Installition took me about 15 minutes.... including cleaning up afterwards!
All you need to do is undo the connector (mine was under the battery), take
the heat shield off (just slips off) and then unthread the sensor.  This
is one of the easier jobs for this car.

WARNING:  For those of you with E-30 convertibles!  The normal O2
          sockets (looks like a normal 22mm deep-well socket but
          with a slot in the side for the wire) won't work!  There
          isn't enough clearance between the exhaust header and the
          side wall.  I bought a special O2 sensor wrench from Snap-On.
          It looks like a thick crows-foot socket.  It cost $26 with tax.
          If you're not anal about this things (like I am), then you
          could use a 22mm open-end wrench or an adjustable wrench.

     Hope this helps!
          Larry.
