Depends, if you work alone in the studio its worth it to pickup a couple of bogen expan drives off ebay. They fit the roll tightly and have a plastic chain so you can control it precisely from the floor.
I generally use a stepladder and feed it from the roll in stages, securing it with a small pony clamp in the end while I pull it tight.
Watch out for the ends, if they get dinged, you have a wrinkled edge on the whole roll.
By the way, 1" emt conduit make a nice, cheap crossbar.
