PSA: A cheap jeweler's loupe saved me from a bad shutter repair

I was working on a vintage Pentax Spotmatic where the shutter speeds felt off across the board. I spent three hours cleaning the mechanism with naphtha and tweaking the spring tension, but the 1/1000 speed still dragged like molasses. I was about to order a $200 shutter timing tester online when my buddy from the local camera club said to try a 10x jeweler's loupe instead. I grabbed one for $12 at a hobby shop and used it to really look at the escapement gears up close. Turns out there was a tiny burr on one tooth that was catching and slowing everything down. A quick file job and it was fixed. Has anyone else found a weird tool that worked way better than the expensive specialty stuff? I'm wondering what other cheap tricks are out there for diagnosing stubborn issues.

A good magnifier beats guessing every time.

Honestly, I learned that one the hard way after ruining a bunch of parts with cheap tools. You really don't realize how bad low-end stuff is until you try something decent, it's night and day. Even a basic jeweler's loupe or a headband magnifier saves you so much headache when you're trying to see tiny solder joints or inspect a board. Ngl, spending like 20-30 bucks on a decent one was one of the best investments I made for my bench.
