Anyone have experience with Beck/Arnley Oxygen sensors?

Part #156-8400 is listed for many MB models that use a 4 wire 02 sensor.

Here is their web page for a reference

Just want to know if I should use them verses Bosch, as they are less expensive.

Thanks

Beck Arnley doesn't really make too many parts. More of a big distributor of smaller OEM brands. Chances are good that the Beck Arnley O2 sensor will be a Bosch.
