The Cell Pearl would be a great addition to anyone's arsenal if they didn't have a pearl ball or wanted a new one. But I still think you could have complete arsenal with the Cell (or Dimension), the Uprising, the Rayzr and a spare ball.

As for Roto-Grip putting out quality products I would have to add one thing to that statement. Roto-Grip puts out quality products at relatively low prices. Sounds like a win-win to me.
