Deciding where to buy Air/Fuel Ratio Sensor

My 2004 Civic EX coupe is giving a code for the #1 (upstream) oxygen sensor.
A Honda dealer looked up by my VIN and said the part # is 36531-PLR-003, which is $341.

Matching it up on Autozone.com (to a Bosch) and a google search on the part# says it's a wideband, however mine looks identical to a narrow band. This (http://i653.photobucket.com/albums/uu256/user-pics/O2sensor.jpg) is mine. How can that be?

The #'s printed on mine are DU2 | Densor | 192400-1170 | 04F14
Denso (densoautoparts.com) shows the #1/upstream sensor is an air/fuel ratio sensor, part # 234-9017. I believe 192400-1170 is a part # Denso has to only be installed/sold by Honda, thus the difference in part #'s (192400-1170 vs 234-9017). Then Honda has their own 3rd Honda part # for it. Confusing.


Looking on Ebay for part 234-9017, there's this one for $135.50
http://www.ebay.com/itm/300914170345
It doesn't list the brand, but I messaged the seller, who said it's a Denso. Why isn't the brand listed?
One feedback comment (for a different item) says:
"It works/fit but doesn't come in a Bosch box / no marking. Likely Counterfeit."
Does anyone know if that's true?

And this one for $145
http://www.ebay.com/itm/300938824320
Which does state Denso in the ad. And this seller has much better feedback.

Has anyone ordered from either of these sellers?
I know most replies always say to not take a chance and just buy from the parts store, Honda, etc, but I already realize that and am only interested in replies from someone who knows more about ebay parts sellers and especially if anyone knows about these sellers in particular.

And Amazon has it for $145, sold by Amazon.

But couldn't it just as easily be counterfeit as those through ebay sellers? One of the reviews mentions part #'s being sanded off, but that could have been when it sold through a 3rd party

Don't you think almost a year later that I would have already bought one by now? FYI, I didn't buy a Honda part sensor. I assume that's what you mean by "factory".

I also get most of my oem replacement parts off rockauto. I will sometime grab the full part number off there and paste it into amazon to see if its on there cheaper.
