Hi William,
Choosing deck can be great fun. Are you making an adventure out of it?
And lucky you. AT is such a great forum to get wisdom from. It was not around when I discovered the fascination of Tarot....
Have you considered apps? I know an app is nothing close to having the feel of the deck in your hand, but many have found it a great way to spend time with the images. Fool's Dog has several of the decks you are considering, plus they have one of the best Tarot app formats available today. They now have 4 samplers, and those are all FREE. Most of the decks you are considering are included in the Samplers. Here is the link to all their decks.

I have both the Steampunk deck and the app. I say yay to both. The Steampunk is one of my favorite apps because the back lighting of the card images enhances it immeasurably.
The book is a good, easy reader.
Druidcraft is super popular. Card stock wise, these cards are big. This is the deck so many did their first trimming project on. I use my deck way more now that it is trimmed. The book is awesome. It is packed with info and quite deep.
Here is the thread of trimmed decks and includes an alpha list of decks. The Druidcraft has lots of samples people have uploaded.

I ordered the Illuminati and it is almost here. I put off buying it until now. I used a 30% off coupon Amazon had running last weekend. That is the only reason i talked myself into it. Many rave about it and say it is one of their very favorite decks. Others say it is very busy. That one is really going to be up to you following your intuitive guidance on whether to get it now or later.
The Llewellen Classic.... I did not even buy the $3.99 app for that one. For some reason it does not feel right personally. The RWS has secrets hidden in it for the seeker to discover. The Llewellen Classic exposes a lot of those secrets, so the adventure of discovering the secrets is lost. This is another one of the decks included in the Fools Dog samplers.
Have fun getting your next deck(s)!!!
