What do you look for in a program?

I'm thinking of working out some contest, not sure how that's going to play out yet though. I want to make it fair for everyone, from the guy with 1 sale a month to the guy sending 15.

I like it when my sponsors have a program where you get paid more for all sales over last month. This gets me motivate to really push that sponsor that month. Say I made 5 sales @ $30 / sale last month and you are paying $50 / sale for all sales over last month. If I send 15 sales this month then I would get $30 * 5 and $50 * 10. The numbers are just examples but it really gets me to push that sponsor.
