Miranda80, in regards to a question you asked: I think whether the meaning changes in different decks depends on the person. I slightly change meanings based on my decks and the picture at hand, but the essential meanings of the cards are the same if it follows the same system. So, as long as you buy a Rider-Waite deck, you should feel it's 'familiar' in a lot of ways. Some people never change meanings. To some, a 2 of Cups is always a 2 of Cups regardless of decks... it just depends on the person. I see my decks as having personalities, so it changes the cards slightly.
I've been meaning to look into the Druidcraft further, too. It looks like a really nifty deck.
