I just picked up something called "Handi-Tak" from my local Target store. The packaging said it is "reusable adhesive replaces tape, push pins & nails." It's supposed to be just like "Blue-Tac", right? If it is like "Blue-Tac", I intend to use it between my speaker stand and my bookshelf speakers. Anyway, the "Handi-Tak" are on sale at Target for $.60/package of 4 pieces.
