As of right now, this is over 500 successful film & video Kickstarter campaigns. It should update as more are added. Perks are grouped, when needed, into the correct bin (i.e. $25 perks include anything in the $20-$35 range).
If you want, I can break this down for you further. Email me (lmcnelly [at] gmail [dot] com) for more info.
