[Hackpack] First price estimate

I completed a first price estimate for a $40 hackpack: https://docs.google.com/spreadsheet/ccc?key=0Akog0JI0-bB9dHphWFdtX1RpUUcxRU… Please give some feedback here or at http://hackpack.me I'm thinking we run workshops primarily for teenagers and sell them to workshop attendees. We could try to get them 50% subsidized, but I feel that it's important that people pay for them so they value them more. -- marc/juul
