I use honigs shin guards and a cheapo chest protector, so I'm also in the market soon for a chest protector. I am considering the:
Schutt -
Schutt Sports: Umpire's Gear - Kool-Chest Protector
I think Schutt has a great appearance under the uniform.
ProNine (already mentioned)
and the Honigs K2 (which I really like but am scared of) -
Honig's Whistle Stop Online Store - Products
For the studly 18's or Mens FP or baseball I use a tried and true West Vest and Gerry Davis Shin Guards.
I use a heavier older wilson mask than these feather weight new fangled masks but I've taken a bat to the face with it and I'm still kicken so I'm sticking with it, so no recommendations for you there.
