Yes, it is--wry humor is hard to convey with text.That's not really "a bit", as most of those cheapo ebay cameras go for about $50 bucks or so. This is $300.
I need the higher quality images to accurately evaluate exhaust valves. Aviation engines are air-cooled, and the exhaust valves take a beating. A failed exhaust valve is a lot more exciting when it happens on a single-engine aircraft than a car. I don't like excitement when I'm flying, so I check the exhaust valves carefully every year, or any time I suspect something might be amiss.
