Sorry - my fault, I was in a bit of a rush. I updated the post, but I meant lowest impedance or voltage.
But I'm afraid I'm struggling a bit to keep up with all the questions and code contributions so I haven't had time to vet any Piezos in particular... But if anyone found any good ones (especially from German distributors because there have been are many Bangles in Germany!) then I'd be very happy to add links to them somewhere prominent!
