I'm seeing $30-$50 on Amazon, the problem is, none of them really stand out except the one lanx linked earlier. Problem is, it's for a iPhone 5, and I have a 5s. One of the questions asked on the page if it would work with other iPhones and the answer was no. So it's just for iPhone 5.
All the rest have reviews of screens being terrible, bad touch, dead pixels, etc. If they guarantee their work, and/or provide some kind of warranty, then I think I'll just pay the $100. I want a new phone, and I have an open Project Fi invite to start saving me money, but I don't really want a Nexus 6, but it bugs the shit out of me to dump more money into a phone I don't really want anymore.
