Tarot cards

[Rokk]

So I was thinking about buying a couple of tarot decks to add to my arsenal. I thought they might be good to use for some mentalism and "spooky" effects to give the trick a more magical touch. I also figured you can use it in performances to switch into a deck with a setup without raising suspicion. And you can find some decks that look really cool to.
But then I saw that they cost at least three or four times as much as a ordanairy deck.

Anyway...
Is there anyone of you guys who owns or uses tarot cards in your performances? Got any suggestions for what I should buy? Is it even worth it to buy a deck? And how good is the finnish and "feel" in those decks?
