I remember most players going for twenty to sixty dollars, the best might break a hundred by a little bit. With just a modest spread in ability there would be a bunch of people that might cash pretty big, enough that might win to keep the calcutta prices from getting too lopsided.
I know I say this in every thread about calcuttas but I like the cash option. The players agree on a set amount, maybe twenty bucks, and everyone that wants in the side pot pays when putting in their entry. The person registering competitors takes the money and adds a name to a list, maybe a minute or two extra at most and now those that want to play for more can.
