I've read many books on complex analysis/variables; Ahlfors, Zill & Shanahan, Stein & Shakarchi, the one by Schaum, Greene & Krantz, Marsden & Hoffman, Tristan Needham, etc...
And this is the best (at least for an introductory level), i can not believe how good is this book by Asmar and Grafakos, please read this one. Furthermore in springer's web you can find a solutions manual to every other odd problem.
It's just a meatter of time for this book to become a classic
