I don't care for the overuse of Autotune in music. To put it accurately, I hate it. But everyone has to polish a turd once in a while. I was very impressed by this plugin. It blows away Logic Pro's built-in plugin that is supposed to do the same thing. MAutoPitch sounds a ton better, and the additional effects like widening are very useful. You can get extremely professional results with it. And it's free, which is frankly amazing for this level of quality. Don't waste money on Autotune when you can pick this up for free. If your needs go beyond what this can do, you should be using Melodyne anyway.
