Replacement sensors are about $50... It is a standard VW part.

I wasn't really concerned with the location... I figure, if the stock narrowband can survive in the header 6" from the block for 100,000 miles, the WB can survive anywhere in the DP... but the hotter it runs, the more often you should pull it out and recalibrate it to free air. As long as the EGTs are <1300F and pipe temps are <900F it's within operating range, right? Either way, you gotta be ahead of the cat... since I'm catless, I just used the rear O2 bung that was already in the back of the DP for my WEGO... then had a second bung welded right next to it for the Bosch.
And Greg was telling me the Bosch WB are like $38 from the dealerships.
That's cheaper than a narrowband sensor for the SVX.
