So why even consider Ziegler whose book is just a watered-down version of Arrien's? It's as shallow as a puddle in the summer.

Both DuQuette and Snuffin are good choices. Banzhaf is better than Ziegler and explains nicely, but I'd prefer DuQuette. IMO it's the best if you really want to start getting to know the Thoth, not only use it for readings and somehow make sense of it with the crutches of somebody else's simplified explanations.
