What did he say is the service cost?
It will vary depending on what the issue is and whether you have warranty or not. I got the P3 from the classies that had the screen issue and sent it in to get the screen fixed and updated software. The estimate was around $35, but I don't expect to get a warranty discount. I would plan on at least $25 plus shipping to him for out-of-warranty work, and that seems pretty fair to me. Your first email to him should give him an idea about what you need, and in his reply back to me, he gave me a list of prices for common services. If anyone has something they want fixed, I would try to get it done sooner than later just because there is a finite number of parts left.
