Stop by your local photo store and inquire as to if they have some expired 120 they would be willing to sell cheap, when I got my first hassy, the photo shop became my best friend, I was picking up 120 for .50 cents a roll, so if I blew one, it was really not a big deal, the satisfaction of throwing a 6 x 6 down on the light table raises the bar considerably, you will have a great time...Just watch out, moving up in size always makes you want to go bigger!
