I'm not a fan of local tuners, not because they can't be good, but a lot of local tuners are either bad tuners or are re-selling stolen tunes.
There are good tuners out there, but it seems MOST of them are bad tuners. After getting tuned, you may not know any damage is being done, but a bad tune can cause $3-15k in damage.
