Just figured out what to get the BiL for his birthday.
Raspberry Pi troubleshooting kit:
✅ Small USB powered HDMI display
✅ Handheld wireless keyboard with touchpad
Enough for emergencies anyway. I have similar stuff and it's really handy.
Apparently the $20 7" LCD screen I got on eBay a while back was a fluke. I'm not even finding deals I like from aliexpress.
