If you can't find someone who can do a good fret leveling and dress, Plek is certainly the way to go. As long as the frets have been leveled and re-crowned well there's no difference between a plek job and a manual fret dress.
I've been told that gibson doesnt plek as designed. They do it without strings on for an approximate load. My local dude, who has a plek machine, went to training in germany and has done a ton of them, thinks the gibby process is lame because it doesnt measure everything the way it was designed to be measured.
