Oh wow I did not think of that. 
Thanks ajspiano!
I punch my sheet music and put it in three ring binders. I have a main one for storing my sheeds by catagory ( main style ) and another one for my little in house performances where I put three or four pieces into that one that I will perform from.
I have a duplexing B+W laser printer to print my sheets with ( It's a Brother HL-2270 DW) that I think we paid $69 for. I do my online statements with that as well.
You can also spiral bind your sheets into your own book. I have a spiral binder and various spiral bindings but I haven't tried it on sheet music as yet. We used to make wedding proof books for our photo business with that. I don't shoot wedding any more but have a lot of equipment.
