Which one is the best textbook for self-studying differential equations?

[Lavabug]

I used a lot of different DE books when I took the course. What I found was: the 2 Schaum's on this subject were really bad, the book by Nagle is ok as a recipe book for anything you'd cover in a semester course (and it sells for 4-5$ shipped on amazon used) but it's a bit of a brick.

The one by Tenenbaum has the best explanations I've seen and has methods I haven't seen anywhere else, I would buy that one if you typically keep your textbooks.

+1 for for Tenenbaum & Pollard. I bought it as a more advanced reference for a course I am taking (which uses Zill - total garbage) and I think it is a fantastic book. Very well written. And its a dover!
