Always thought borescopes were extra until I spotted a deep crack nobody else saw.
It was in a spot you just can't see with a mirror. I won't skip that step on an engine inspection now.

Found myself in the same boat last year checking a cylinder. That little camera showed a tiny flaw on a piston crown I would have sworn was clean. Completely changed my mind about them being a luxury item. Now it’s just part of the regular process, like putting on safety glasses. Lets me sleep better knowing I didn't miss something hidden. The upfront cost feels minor compared to the headache it can prevent.
