Dust blower vs. air compressor, which one actually saves you money in the long run?

Stopped by a computer repair shop in Austin last week to grab a used fan for $5. The guy behind the counter was blowing out a motherboard with a pancake compressor. He said he's been using that $80 compressor for 6 years instead of buying canned air at $12 a can every couple weeks. My buddy swears by a $25 electric blower off Amazon, says it's quieter and good enough for his home rig. But I've seen both strip screws and push dust deeper into PSUs if you're not careful. So which route has actually worked for you without wrecking parts, and did the upfront cost really beat the canned air over time?

Pancake compressors definitely work, but the strip screw thing is more about technique than the tool itself. You gotta hold the nozzle at an angle and not go full blast into every crack, that's just common sense. The real money saver is one of those $30 handheld electric blowers, not the $80 compressor, because you can use it inside without sounding like a jet engine. I've had mine for 3 years and it paid for itself in like 4 months compared to canned air. Compressors are overkill unless you're blowing out car interiors or doing heavy shop work, and they add moisture to the air unless you got a dryer on it. Stick with the electric blower, it pushes enough air for PC guts and you wont bust your eardrums.

wait, so youre saying the moisture thing isnt a deal breaker for you? cause ive seen people wreck motherboards with compressor air even with a dryer attached, and that static plus water combo scares me way more than the noise. dont get me wrong, the electric blower is fine for dust bunnies, but how do you know it actually pushes out the caked on stuff in a PSU without taking the whole thing apart? seems like both tools have their blind spots, just depends on which risk youd rather take.
