looking for a new toy for us.

We have tried the vibrating beads harness that fits around her and liked it...but it pinchs. I am trying to find a toy that will give the same/similar feeling to her that will not pinch. I have had neptunes sheath get my interest but I am wondering it it is worth it. Anyone have some experiences with it...good or bad? The beaded harness gave her great joy but the pinching would nearly kill the mood.
