Ebay O2 Sensor

[tiwebber]

Hi folks. I am having idling problems with my 1990 300te wagon. It been diagnosed as having need a new O2 sensor. The mercedes dealership wants 330 canadian dollars for the replacement part. (approx 280 usd).

I have looked around and can find a Bosch replacement from many places online for about $130 usd and on ebay there's one for $35 usd. The seller describes it as "O2 OXYGEN SENSOR BECKARNLEY SG505 M. BENZ 300E L6 3.0 Item number: 8051482403 this item will work great on 90 MB 300te"

Is this a reasonable 02 sensor to buy?

Much appreciated.
