There are a couple I'd get if I were you.
1) Heirloom: Photo card prediction that lives in your wallet.
2) Freaky by Greg Wilson: Classic Copper, Silver, Brass effect using house keys instead of antiquated coins no one carries around anymore.
3) My Pet Boris For the Iphone or Android: It's an updated The Web by Jim Pace for the 21st century.
4) Hopping Halfs by Johnson's Magic: The classic "two coin trick" with a trick ending. Lives in my coin purse that lives in my right pants pocket. Resets in seconds.
5) Exact Change by Greg Wilson: Another deadly powerful close up/ walk around wonder.
6) I usually keep a Free Will prediction written on the back of a business card that lives in my wallet as well. The Key/Coin, Pen, Wallet trick. Unfortunately I don't know what the trick is called on the market, I know it's commercially available and that Rick Everhart performs it, I just know the method and have adapted it to suit my needs.
7) Hundi 500 by Greg Wilson, Cinch by Shaun Robison, 1 to 5 dollar bill, or other similar bill change.
8) Fire Wallet, Peek Wallet, Utility Wallet, Impression Wallet, Multiple Out Wallet, or other similar magicians wallet.
That right there is more than enough to keep you going for a bit!
