Auto Tune EFX or EVO?

After working on a song with another vocalist, I attempted to use VVocal in X1 in a pinch to fix a few pitch issues (there was no time to do repeated takes to get it right)......it really didn't work for me....
I downloaded the Melodyne demo but it looked too complicated to learn within my time frame.....how about Autotune EFX?
I need something that's simple and will get the job done quickly.
It seems like EVO has bells and whstles I don't really need.....does anyone have either of these Autotune versions......good sale now at Audiomidi
