Glad your back on the road! Sounds like you paid a very reasonable price for the repair! No personal experience BUT a friend went over to another friends house to 'help' him replace a water pump on his car (just for the price of a few beers). Well, turns out those beers were the most expensive beers he ever bought. Yep, snapped a bolt off below the face of the W/P flange (just below). Had to take it to a mechanic to remove the stud, and install the W/P. Friend never asked friend to help with another mechanical problem (especially if 'beers' was in the process). Lesson well remembered. As a footnote, forgot to mention the snapped off stud was at an angle, and those who looked at it were not wanting to tackle drilling on an angled stud (below) the flange, hence the tow and mechanic fix.
