Great O2 Sensor Deal
Auto Medic Supply at http://www.oxygensensors.com/ has a great price and sensor for the FD if you want a one wire like the stock unit.
I just had one sent to me for $34.99. It has a 20" long insulated lead with a stock Mazda connector on it. It is made by NTK which also makes the stock Mazda O2 sensor.
You can find a car's sensor by make,model,and year; or even Mazda part number. I got their part number 250-21020, which is listed for a 1994 Mazda RX7 R2-1.3L.

I'm not sure if they ran out of the NTK brand but it looks like the one they are selling is made by Walker.

Are these Walker O2 sensors as good as the Bosch's though?
I am ordering a Walker just to see.. need to change my *ORIGINAL* one anyway. LOL
I pass emissions fine though with the current sensor...
-Kib <-- not sure if I need a new one.. but better to be safe

OEM equipment associated with air pollution emissions such as the Oxygen sensor must be warranted for 50,000 miles. I believe this is some sort of law imposed by the air pollution control officials.
The replacement available on the web site referred to in this thread is also warranted for 50,000 miles.

Just ordered one also. Note that the web site has the Walker unit, part no 250-21026. I called, and he has a few 20-21020 still in stock (one less now 
) At this price, I could give a rats *** as to whether my 60K mile unit is fine or otherwise, though I think I'm running rich 'cause my mileage is about 14 mpg (looking for 17 with light around town driving with a little freeway mixed in on a STOCK set up, only DP replaced) and the turbo housings and DP will GLOW in the dark after just lazy loafing driving home, AFTER I've cooled it with the fan on for about three minutes. Anyway, just mentioning that the part number that started this all DOES exist

And more...
Mike, the fellow at Auto Medic, wanted to know if this really IS the correct part number. He had me look up the part for a 91 ford probe 2.2L, and the picture looks just like the unit I pulled out when I changed my DP. I figure for 36 bucks, I'll throw it in and if it somehow isn't correct, I'll put the old one in and buy the Walker unit.
Wasn't the ford probe made by Mazda then? Shares a body with a mazda product, right? I've seen a Haynes manual for the probe and a mazda car, all wrapped into one. Hmmm....

How is this posible when the OEM O2 sensor is $175.72!
That's an ablsolutely disgusting, insane markup! 
Well I checked out the site and it says "OEM STYLE" key word being style (= replica)for $47.99 but that's still less than 1/3 the OEM price.

So I just installed the NTK unit listed at the top of this thread... what a difference! Car idles smoother, and is much more driveable in the lower rpm ranges. Very tractable, as they say. This was the part number 250-21020 for 36 dollars!!. The connector is absolutely the same as what came off my 93. The sensor body itself is a little longer than the stock unit, I'll post pics if anyone is interested. The wire even had the heat shielding, in a nice blue color! Soooo happy cewRX posted this!!!

The 47.99 price is for the Walker unit P/N 205-21026. I haven't seen the picture for this, whereas the picture for the 250-21020 looked Just like what my original looks like. Plugs right in, too. What the parts manager and I noticed was that the 250-21020 is a crossover part for both Fords and Mazdas. Anyway, has anybody seen the Walker unit yet? How close is it to the original?
