Hi MagicMatt...
That's kind of like asking "does anyone know of any good films?"
There are
loads of ways to achieve this effect. What you choose will depend on your ability with cards, particularly in terms of whether you can p*** a card or not (and if you don't know what that word is, you probably can't). If you're buying a special wallet for the trick, it's important to check whether you need to be able to do this or not.
There are ways to do this without using this technique (the Mullica Wallet is favoured by many professionals). There are also a lot of ways to do it with a normal wallet.
My advice would be to buy either the card to wallet book by Jerry Mentzer, or the Card to Wallet DVD in the "World's Greatest Magic" series. These will demonstrate lots of different possibilities using different methods, and give you an insight into what gimmicks are available.
Finally, if you want to go down the route of a gimmicked wallet, be aware that many of the traditional products look like formal evening wallets, i.e. huge old man wallets that will look out of place for a lad of 14 years old.
Hope that helps.
