Generation IV External Engine - best wide band for the hp tuner pro?

Ok I been doing some research. I'm curious witch kit to get for my hp tuner pro.. any of you guys used any of these before. I heard the NGK is really good but I would like to compare it to the AEM
LC1 for $139 or NGK AFX for $239!!!
Then I found an AEM wide band kit with guage for 165$

The AFX is actually produced by ECM, the manufacturer of top quality lab grade equipment used by the OEMs (such as GM), and then marketed under the NGK brand name. It's the best system you can get for under $1,000.

Ok thanks... I really didn't want a single gauge pod set up that the AEM would require me to do with this kit
