I have been to a few weddings with this and, without a doubt, they are the hit of the wedding LOL. I have had to wait in lines to use one and then married folks I have spoken to afterward say they look at the photobook pictures over the actual wedding photos. And, honestly, 500-800 dollars really isn't THAT expensive when you are looking at the price of the entire wedding as a whole.

This is worthless since you said you are already ordering, but I say good call
