"Best" cable elevators?

I'm using chopsticks (left over from carry-out Chinese) lashed together with rubber bands. Not sure how much they're really contributing to the sound, but they do elicit comments from the civilians. ("What the hell are THOSE things supposed to do?")

Non-DIY recommendation: "Cable Elevators" from audionut.com -- work great, with a very clean look.

$160 for a set of 8. Use them myself.

You can use the side indentations for additional wires or power cords.

I am currently using folded pieces of corrugated cardboard to elevate my speaker cables and power cords. In my system, they seem to restore intertransient silence (i.e. the carpet sounds like it was blurring the sound of my system).

Anyone know how much difference I could expect by upgrading to terra cotta pots or the wooden dowel teepees?

Also, what is the minimal and "best" distance from the floor that others have found?

Thanks in advance!
