Hopefully you're already aware, but
SparkFun is having a pretty ridiculous event tomorrow - they're giving away $100,000 worth of stuff, with a maximum of $100 per customer. With only 1000 or so people getting anything free, I'm dubious that it will last very long, but that's not going to stop me from sitting in front of my computer, mouse finger ready, at 9am MST tomorrow morning. I am going to try to snag some wireless boards and maybe some of their button pads... but I will have to make another survey of the site to decide for sure. Be sure to post if you manage to get anything!
