Bought a cheap camera scope for $80 and it broke after two inspections

The lens fogged up inside a warm flue and the image went completely blurry. I had to redo both jobs for free. Anyone have a good brand that can handle the heat and moisture?

Learned that lesson the hard way myself with a cheap unit. You really need something sealed against moisture and rated for thermal shock. Look for inspection cameras specifically built for HVAC or plumbing work, they cost more but don't die in the field. My Bosch has been through some steamy pipes and still works fine.

Yeah, the thermal shock rating is key. I fried a cheap one going from a cold crawlspace into a hot furnace exhaust chase. Condensation killed the board. Now I just look for that IP67 rating and a decent temperature range on the spec sheet.
