I bought mine from this outfit 2 years ago for about the same price--I highly recommend the shoe for comfort and its light weight.
If you are concerned about "feeling" the ball when it hits your CP, then the Gerry Davis protector is not for you. I use one, and love it, but I only do LL/12U, and I have "felt" a number of shots off the chest/breastplate part of the CP (the shoulder protection is quite good, however). None hurt, but I did feel them. If I ever decide to move on to levels with faster pitching, the Gerry Davis protector will stay behind.
