couple of observations I have had.
Ruth Niles has a new stainless steel one that "stands on its own" - it has a flat spot that allows it to stand on the counter without a display. Which solves, what I feel, has been the biggest complaint (if you will) from people that have reported back to me.

They buy (or receive) these beautiful stoppers and they end up in a drawer somewhere. I try my best to make little stands to sell with my stoppers - at least I know theres a chance they will get to see it more than once in awhile.
