Default Tuning fuel mixture EGT or Oxygen sensor???

Has anyone went to oxygen sensors for tuning fuel? I've been using EGT, but when you get to fat the temp on the EGT is showing that you are to lean, because the fuel is burning in the header. In talking to a racing friend, he had said that using a oxygen sensor with a logging system is alot more accurate and didn't cost to much more than EGT, especially if your running a direct port nozzles where you really need to have an EGT on each port, in case one nozzle get plugged. Do any of you know what might be the best system at the best price?

What fuel?
I also think tuning with a Air Fuel Ratio Monitor is the way to go.
But I personally don't have either.

O2s are definitely better for tuning the fuel system.

the o2's are better IMO also although I dont have them I've seen several. I can tell ya to stay away from the cheaper ones that auto zone or parts stores like that sell they are cheap and not accurate.
