I get mine at the local Lowes Home Store - it's blue carpet tape, and the brand name on the inside of the roll is Shuretape - comes in 1-1/2" and 2" wide rolls.
I use a very tenacious double sided tape used by wood turners from my local Woodcrafters store. It's quite strong and as Mike said, be careful prying a flexible object off of the tape. Acetone or alcohol helps remove it. I have a steel plate glued to a hardwood block under the tape and it reduces any vibration. Usually, I can remove the object with a thin, sharp, wide wood chisel slid under the object slicing thru the tape.
