Full guitar setup I did for a buddy of mine, which included new bridge installation, new tuners, fret leveling, new electronics and of course new set of DiMarzio pickups set us back only couple of hours, of which the fret leveling took the majority of the time.
I'd like to observe that and critique the results.
I wish you were there, it'd have been more fun, or you could have jumped right in while I'm drinking some beer. Regardless, the guitar was awesome afterwards, very playable and sounded really sweet, and it was a cheap washburn too. For fret leveling I just used sanding beam, since it didn't require that much, well, leveling. I'd like to think I did a pretty good job, specifically because I am self-taught and only had prior experience from dozen something guitars I did for myself and some other friends.
Plek machine would have sorted out in mere minutes.
Kicker here is (back to topic), someone qualified for repairs, someone that does it everyday for the living, would be able to do it in even shorter times, and probably better too.
