What to get with my Dangerous Prototypes Free Coupon?

Over a month ago I won a coupon for a free PCB from Dangerous Prototypes. They give a chance to win a free PCB coupon three times a week on their blog page, on Facebook and on Twitter. Once in a while I make a random comment to try to win, and finally I did.

Now what the heck should I buy? I'm really having a hard time deciding.

Top picks so far are:
