I'm fine with "naive" set theory and low level mathematical logic, however I want to understand set theory in particular at a deeper and more formal level. I want to learn more about cardinals as well as other higher order sets and about proper classes and formally handling them. It would be nice if the book had a formal definition of ZFC and also talked about maybe a few other popular extensions of ZFC like NGB or something. I know anything like this is going to require some more advanced mathematical logic that I may not have, so its fine if it has to go over that in some detail. However I want to try and maximize the ratio of set theory to mathematical logic as much as possible. Now I'm not sure where to start looking so if anyone experienced in these subjects could recommend a book to me, I'd be very grateful.
