Free Give-Away: What would you want?

I'm debating on hosting a contest soon and wanted to ask the community what you would want as the prize/give-away for the winner. I'm thinking a pump, dvds, balloon magic subscription, or possibly even a registration fee to twist and shout.

No matter what it is, please let me know so that I can begin negotiations for attempting to get a prize for us...

Also, what should be the contest? Any suggestions?
