UPDATE: i found that you can get this from Amazon sellers, just put in.... 3M Dual Lock - SJ3560 1" wide in your Amazon search. Remember that if you get 6 feet, that is only really 3 feet after sticking together. It will run you about $21.00 for 6 one sided feet.
I love this stuff. It holds my Mini 0803 in the rear and my Mini0806 in the front and allows me to swap different cameras easily to test and make notes on them.
