My buddy has a $6000 projector. He found it in the trash. The only thing wrong with it was a cracked solder on the power supply.
Similarly, I have a $5000 audio console that I got for ~$100 in parts; it had a bad power supply. Honestly, probably just a bad capacitor on the power supply, but I didn’t feel like desoldering every capacitor to check their capacitance. Diagnosing the power supply took about 5 minutes, and most of that was just finding all of the screws that were holding the case together. A quick read with a multimeter told me everything I needed to know. Swapped out the supply, and it has been working fine ever since.
I can top that. I got a broken $100 BlueYeti microphone for $10 on eBay. The USB cable they shipped it with was bad.
