Photo Booth Rentals

We are renting a photo booth for our wedding, so the guests can get great pics to take home and we get an amazing scrapbook of pics and signatures of all our guests.
HAs anyone used anyone. I have located a ton of them and they all vary in price.
We would like to try and stay in the 1500-1600 price and need it for 5-6 hours.
Please forward info thanks so much
