Excellent mathematical logic books

[Eph]

I am looking for excellent mathematical logic books that start from the beginning and go to the (what we think is) the end.

Hopefully something with lots of editions so I can pick up a 2nd edition for 3 bucks on Amazon used.

Ideas?

I think Robert R. Stoll's Set Theory and Logic is pretty good and it's often available at Barne's and Noble so you can take a look at it first.
