I don't know what they get paid (your number sounds about right), but they do work 90/90. Mostly an older crowd that has been here for years and really know the airplanes. Phases come every couple weeks and they get done in 12 hours. If you call ahead with a problem they'll have the panels off and be elbows deep in it before you even collect your trash and get out.

I can't think of anyone that doesn't think highly of the mechs.
