Which book can be used as an introductory textbook in complex analysis?
I have some choices (more suggestions are welcomed)
Marsden & Hoffman
J.B. Conway
Ahlfors
Palka
Lang
Stein & Shakarchi
I want a textbook which is affordable,builds my concepts and lays a strong foundation of complex analysis.the book should cover the concepts that are needed in a complex analysis course in a formidable manner.Also it should be such that I can use it for an exam
Also I would be happy if someone can provide me a reference book that can be used side by side with the textbook for studying in more detail
