Question for custom board makers

[RavennaAl]

I know that most guys who make custom big boards are using fiberboards for the playing fields and some guys are using metal. My question is, has anyone tried using plexiglass? I've been thinking of making my own large board, only because I can't afford the $400+ that most of them cost. So, I was just wondering if plexiglass would work????? If so, how would it compare to metal or fiberboard?
