I-touch repair

Hi all, my daughters I-touch is giving her trouble. All signs indicate that the head-phone jack needs help due to intermittent sound when moved around. I doubt warranty is an option due to its age so I was wondering if anyone here had the pleasure of doing business with a repair service. I see there are a bunch of them when searching the net. Any pros or cons about any of them would be a help, I like to hear when someone has a good experience with a service. It makes me feel better about sending something like this to be repaired. Thanks
