I began advocating converting all the old polaroids, both roll and pack, to film a year or so ago. Put it on my website, then mentioned it on forums. Then I creasted a CD that is a diy, not a 400 dollar conversion camera, just buy one and do it yourself instructions thing. I sell it on ebay. So now the price of the cameras on ebay have trippled and I get emails a couple of times a month asking for help. I can't afford to buy the shells anymore. Holy moly what have I done. I love that people are finding a use for the cameras, but I should get a special discount on mine. Don't guess that is going to happen. By the way if you own a couple of pack cameras how about selling me one cheap lol.
