Quantum Field Theory Book(s)

[MalleusScientiarum]

Can anybody recommend some good quantum field theory books for introduction to the subject? I am already familiar with some of the techniques from applications to statistical mechanics, but I would like to see them in a different context.

I like a book by Halzen and Martin. The title is "Quarks and Leptons", but it gives a nice physical introduction to QFT and QCD that is rigorous, but less mathematical than most treatments. It assumes you have a good knowledge of QM.

How about a qft book that's specifically useful for cm physics?
