Wohler Inspection Camera

I’m thinking about purchasing an inspection camera. We come across 1-2 jobs per 6 weeks where I know I could sell a drain inspection. I’ve looked at the Rigid line and seems for around 8k you get a decent setup. Plumber buddy of mine showed me his Wholer 350 which looks like a good setup.. runs about 6800. ANyone here have experience with one?
