For many years I was strictly a "tarot" person, but I have branched out a long way since then. The key is to not try to fit any oracle into a given system (such as tarot) as they are usually designed differently and work with their own independent systems. I have also found them to usually be simpler to learn and just as effective as my tarot cards.

How about the Tao Oracle? It's by the same artist who did the Osho Zen Tarot.
That is what I was going to suggest too *LOL* for the same reason.
Other oracles I would suggest based on my experience:
1. Froud Faeries Oracle (you have to have a real open mind to work with this one as it actually comes alive ... don't ask, just go to the study group and browse the threads). There is no other deck, or oracle like this in my opinion.
2. Way of the Horse - amazing for self improvement, transformation, and healing. I cannot recommend this deck/book set (or her other books) highly enough.
3. Animal Dreaming - I love going "walk-about" with this deck and connecting with the animal energies. Animals are divided elementally and it is great for card of day type readings (for me that is). I like focusing on the one animal energy at a time, though I have done larger card readings which came out nicely.
4. Fairy Ring - I love how the deck is broken into the seasons. Though this is a deck that I find about as intuitive as a door nail, and always use the book, I find that in tying it all together this deck is really fantastic. I have a peculiar way of reading with it, which requires a note book and pencil and sifting through its book then putting it all together, but the results are amazing.
5. Victorian Flower Oracle - I suggest getting the kit with the book, particularly if you are not well versed in flowers. I am not well versed in flowers but have really learned to trully enjoy this oracle.
