EGR Position Sensor...?
 

I am having problems with my 2000 V6 Mustang and took it in for a diagnostic test, I was told that one of the problems was that I needed a new EGR Positioning Sensor. Does anyone know where I could purchase one online (the ford dealership is charging a fortune for it)? And how much SHOULD they run for? I am planning on doing most of the work myself with mechanic buddies helping out, but this is an area I haven't tackled before, any suggestions? I am also changing the spark plug wires, I know there are some differences in the mustang setup from other cars, is there anything I should be careful to watch for?

Thanks in advance, and I apologise if this is in the wrong forum, I'm new to the site.
