You can do this yourself.
The front O2 sensor is easily accessible from the engine compartment. If you don't have an O2 sensor socket, you can just snip the wire and use a regular deep socket. Soak the threads with WD-40/PB Blaster for a few minutes before trying to loosen the sensor. Also, put antiseize compound on the threads (don't get any on the sensor element) before you put the new one in. The wires on the sensor go to a snap on connector (just follow the wire). Take your time when you pop the connector so you don't break the little plastic tabs. In a perfect world, this is a 5 minute repair.

Easy - just depends on the condition of your Bung.
Spray it with liquid wrench, let it sit overnight... get a 22mm O2 Sensor socket (allows room for the cable), atached to a breaker bar.
If it's too tight, you can try to heat the bung (the area where it screws into the cat) with a blowtorch carefully for a minute or so before-hand. The heat causes the cat threads to contract, helping to loosen the sensor.
Unplug old, plug in new, screw in new (with a dab of anti-seize on the sensor threads.

What engine code do you have?
ATW's can use the $25 sensor from impex. All other engine codes need the right sensor- which is generally $$. It either works or it doesn't, no need for a review - do not try to splice a generic one in.
