I have to agree with Richard, the Pamela Coleman Smith Commemorative. It's even come down in price.
But you need to take a look for yourself because every deck speaks to everyone individually. Google RIDER-WAITE-SMITH TAROT DECKS & CLONES and you should come up with some good links with images of all available. Don't forget the Illuminated Tarot. I'm afraid to give a link, even though it's not my site, but if you google "Illuminated Tarot" it should come up at the top.
I couldn't imagine having that as my primary deck, but if bright colors speak to you, consider that or the radiant tarot. If you like pastels, consider the Universal Waite Tarot. (The colors are nicer on the full sized deck, but they also have a pocket sized that I use all the time.)
I personally like the PCS commemorative because the card stock is thick, and the colors are beautifully muted, old world style. Colorwise, the Orignial tarot is nice like that as well, but it's glossy, not matte, like the PCS, and the card stock is not as thick.
Good luck with whatever you choose! Keep us posted, and use it in the best of health.
