For under $100 you want to either find a good used bat or find a bat that this not the latest years model but still new. Tons of websites out there to choose from. Locally if ind the best at Better baseball that moved to delk/south cobb drive.
TPX maybe slightly over $100, but good money and they last for 2 or 3 seasons, they dont lose pop very fast. Demarini also has bats around that range. Vexxum I believe.
I bought a WHITE EXO for 50 dollars brand new at our local Hibbets and that is a hot bat..Search the web and try Play-it-again Sports if you have any around..
We are having a bat sale and have several options under $100. Please call me if you have any questions: Ronald Brooks, 678-903-0024 Elite Sports East Cobb
