1. A nice camera. I have a little Canon digital that works great and has decent battery life and good zoom for something that fits in my pocket... but nothing really compares to a camera with actual lenses. And more focus settings. And the way you can just hold down the shutter and take multiple photos. I might actually get decent shots of animals that refuse to hold still. Or at least I'll get some really hilarious photos of animal faces.
2. A kayak. OK, this might require a large storage area....

4. A new computer. I really can't operate on 2 gigs of RAM anymore.
5. A steel string or electric guitar. I have a nylon string guitar from... the '80s? No matter what I play, it always kind of sounds like crap. I realize some of this is due to my skill.
