In the Tarot Deck section is a sticky of sites that list the whole deck.
taroteca.multiply.com is almost a library of tarot decks and you can spend hours looking at them and finding ones that appeal to you.
While you are looking just see how the cards speak to you. More than discussions about the decks, I like to see the cards used in readings and how well they work as tarot, I mean in Your Readings. Online reading places, like tarot.com or facade.com show the cards, but the meanings are standard blurbs and don't vary no matter which deck is used. Some decks are called tarot, but don't read that way. So basically when you are looking at those cards, what do they tell you (without looking at the interpretation?) What appeals to you? What in the deck turns you off? It's all individual tastes, so what some may rave over may leave you cold... visa versa. It's good to find out what other people like or dislike about a deck, but ultimately what will matter most is how you feel about, because you are going to be reading with it, not anyone else.
