Recursion theory text, alternative to Soare I want/need to learn some recursion theory, roughly equivalent to parts A and B of Soare's text. This covers "basic graduate material", up to Post's problem, oracle constructions, and the finite injury priority method. Is there an alternate, more beginner friendly version of this material in another text? (At a roughly senior undergraduate or beginning graduate level of difficulty, although I wouldn't necessarily mind easier.)
For example, one text I've seen is S. Barry Cooper's book, Computability Theory. Is there anybody that has read both this and Soare, and could tell me about their similarities/differences?

As of 2012, Rebecca Weber has published Computability Theory via the American Mathematical Society. The book covers Post's problem, oracle constructions, and the finite injury priority method, as well the arithmetical hierarchy and current areas of research. I am currently using it for a senior undergraduate computability theory course, and for the function, it works quite well. I would say that using Soare's book as reference for more detailed proofs has been just under necessity to fully understand the material, however.
