Blu-Tack where to Buy?

You might want to check another option: look for a Henkel product: Pritt Tak. This is what I use because Blue Tak can not be found in my country.

There is also a product called Museum Wax, for securing knick-knacks in earthquake-prone regions like CA. About 6 bucks for a half-pound jar!

thanks all, i picked up some "tac n stik" for $1.29. Its blue and it isn't tearing off the rosewood veneer of my speakers!

Doug: I never picked up the real deal to compare (though I am comparing a piece of plastic laboratory tubing), coiled flat, to Vibrapods (under my tube amp) as we speak. One thing that you DO NOT want to try under speakers is florist's clay.
