That Reno parts guy saved you $589 and you still sound annoyed about the four months.

Riverside Drive guy probably has 40 apps and still can't find his garage door.

Man, I feel this in my soul. I dropped my grandfather's old Starrett combo square on a concrete floor about five years back and swore it was fine, then spent a whole weekend chasing gaps on a mitre sled. Turned out it was off just enough to drive me nuts, and I only caught it when I checked it against a machinist square a buddy loaned me. Now I keep that Starrett in a drawer wrapped in a rag and use a cheap Empire for everyday stuff, since the beaters are the ones that get dropped.
