The other thread about what everyone wishes they could have made me post this.
I wanted a traditional photobooth too that you can rent, but couldn't afford it, so I'm compromising.
Now, I am setting aside a small corner with a backdrop put up (I'm probably going with a patterned bed sheet, but it could be whatever you like) and having a table with a bunch of fun props. hats, chalkboards, etc.
I found these websites helpful:

Anyways, just in case you hadn't already thought of it, this is a way to have a photobooth without really costing very much.
We have a friend who is going to take pics at it during the cocktail hr and then we plan on sending pictures to everyone.
