I found some based out of Rochester for about $600 - just google "Photo Booths in Rochester, MN." I'm not sure where your reception is at, but you may have to pay a little extra for travel. HTH!
How about a studio-style photo booth with your own photog? Ours did this, his assistant ran it. No pics to take home, but it's fun and they are posted on the share site along with the rest of the pics.
We used Shindig Photo Booths, $400.00 for 3 hours. I think you can get extra hours too. Loved it!!
