Thanks JamesDean, I got the Bosch Mustang O2 sensor for $39.99 as well. The mating connector was the extra $15 (actually $13.50 as I rounded up) because if I ever have to change the sensor out again I want to be able to just go out and buy another Mustang sensor without having to cut & resolder. Still a hell of a lot cheaper than going OEM.
