Can anybody recommend a good introductory book on Quantum Field Theory? Right now the best I've seen is the Mandl and Shaw (which is unfortunately out of print) and the Zee QFT in a Nutshell. Are there any better books for someone who's never seen the subject before?

as a very first book for someone who has never seen the subject before, i think Greiner and Reinhardt is a good pick
