Oxygen Sensors - What and Where?

Ok I have headers that I am going to put on (and hopefully do entire exhaust) But anyways I figure if I'm going all out with exhaust why not replace my 13 year old oxygen sensors. I know where they are, how to replace them, etc. My question is what brand is best? And where about's would i get them cheapest? Thanks guys

NTK sensors. One of the best. Or you could just go with motorcraft.

Oh yeah. Only replace the ones before the cat to save money. The rear sensors only monitor the efficiency of the cats.
