I play in PDGA tournaments either Advanced or Intermediate for plastic. I play for the player packs, the mercy voucher pay outs. Obviously I play for fun, but I spend about $1000 per year on tournaments as a way to have, fun, improve my game, meet competitive players and movers/shakers in DG, and to acquire a library of discs. I look at it like: pay $20-40 for a tournament and come out with a disc is better than simply buying plastic.
I would be upset to compete for trophies only and would severely curtail my tournament play...
