I dont have anything available. However, I have used the evil energy 3in stainless butt band (~$20) and narrow band clamps (~$18 for a two pack) from Amazon with good success. I tend to stay away from the U-Bolt type clamps as I've had mixed results. As Unbroken mentioned, you might be able to find stuff locally but that depends on your area. I'm lucky enough to have a Jeggs local to me so I usually head there in a pinch.
