i second tristan needham's visual complex analysis.
some other good ones:
* the one we used in my undergrad course was fisher's complex variables which is great if you're learning for the purposes of applications. it's a cheap dover book.
* rudin's real and complex analysis (if theory is your thing. note that rudin's books, while great, do require a good background in math).
* as the article mentions, eli stein has a series of books on the four main branches of analysis. i believe the second book is on complex analysis.
