vibration pulse

I have so many vibrators that I could probably open my own store. The reason being because I have a "vagina of steel" and is very particular to please. I am always trying to find that vibrator that has that deep vibrations, very powerful and has a narrow end for pin pointing a spot. I use to use the couture because i like the vibration and power of the couture and it did have the round top, but I fixed that problem. I used the head from a different vibrator that had a nob on one section of it, and because it was made out of silicone rubber and I could pull it over the top of my couture. And WHAM I had the perfect vibrator, UNTIL my cat chewed the nob off when I put it down. I don't remember what old vibrator that rubber head came from ( it was yrs. ago)to buy another, so now I'm on the hunt again Does anyone have any suggestions? less
