I've got the iFixit repair kit. So far I've used it to repair a kindle hdx, a samsung android device, and an iphone 5c. Basically I just wait until a friend breaks their device and fix it for free. I got a free kindle fire HD out of the deal anyway. I don't ask for money since it's usually friends. I've also used it to replace the battery in my lenovo p500 which does not have a removable battery i.e. you must crack it open.
