I started off as "Freemium" player, but changed to what I like to think of as a "Subscription" player sometime last year. My "subscription" is $1/week on a Golden Scratch-R! I think I purchased donuts directly once (during the Gil promotion at Christmas when Scratch-Rs were temporarily unavailable).
Given the monthly costs of games like WoW and the upcoming Elder Scrolls Online, I like to think $1/week is cheap.
My wife also follows the same model that I do.
My daughter is too young for in-app purchases, and I don't know what she does with all the free donuts given out... I think she rushes stuff.
