My league plays for what I would consider a pretty good sum of money but we also have a trophy as well. So we give out both. Some people like the money better others play for the trophy. A quick google search will bring up a number of different companies as well as different types of awards.
I have seen other leagues give away rings and even home made trophies, spray painted beers cans etc...its really how much money you want to spend and how professional you want your league to be. Good luck... I'm out of my league already, pretty pissed, Maclin screwed me last night.
