o2 sensor

what is the correct 02 sensor for my 2005 pontiac montana 3.4 and where can I find the best deal, without losing quality

I'm not sure what you mean by "correct"? Any auto parts store can supply one along with numerous online sites. In addition the vehicle has two O2 sensors, which one are you trying to replace?

I want to replace the upstream one the part stores want 55 to 60 bucks and I see on line I can get one for 25 to 30 but they are not the same brand the parts stores are selling, so I would like to know what brand is good that is available on line, I would imagine some are better than others that is what I am asking.
