Just looking for advice on what would be a good general text for set theory? I use it in mathematical logic a good deal, but have never actually taken a comprehensive course in it, and since I'm going to be tutoring undergraduate logic next year, I would like to have a fairly comprehensive knowledge of at least the very basics.
I've looked WVO Quine's, but it's a bit too philosophical for my current purposes...
Also, if you would suggest an online course or another way of learning it, I'd be interested to hear. Just want to buy a book, or find somewhere to start making some notes from really.
Thanks a lot
