How cool is it to have a photo booth at your event?! It could be a bit on the pricey side, but if you have the budget for it, it will surely be a hit with your guests! You can have the photo booth instead of purchasing favors for your guests. They can even add the photos to your guest book and it'd make a great keepsake for you for years to come. If you have kids at your wedding, the machine will also keep them entertained for quite some time.
Here are some links to photo booth rental companies you might want to check out:

For other locations, you can always google "photo booth rental"
Some companies, such as Auto-Photo, also offers something called a Sketch Express. Instead of the usual black and white or color photo strips, the machine generates 8.5" x 11" sketches of your guests. There are different artist, styles and caricatures to choose from. Nice 8" x 10" gold cardboard frames are also available at an extra cost. I have requested a sample to be mailed to me. I will post a photo of it once I receive it.
