Ends 10/4. Newegg has the Canless Air Systems O2 Hurricane Computer Duster for $55 with free shipping. Electronic air duster is a rechargeable alternative to canned air dusters.
this model is pretty weak... i'd liken it to canned air that's almost all used up, in terms of force. It'll blow the dust around, but it won't power through it like a fresh can. to get any decent power, you'd have to step up to the industrial model, which is over 100.00. The only convenience is that it's cordless. If you don't need cordless - the datavac ed500 is a 500 watt air blowing monster... Love mine.
Sadly, turning this upside-down does not release supercold liquid, and thus does not allow you to freeze spitballs
good link please?
Does it really provide hurricane-strength airflow?

Why do you need something that blows? Use something that sucks instead.
Use a small handheld vacuum instead.
^ Sucking air can't pull dust out of crevices nearly as well as you can blow it out, achieves far lower directional velocity all else being equal.
I haul dusty cases out to the garage and hit them with compressed air from my ancient B&D Air Station. Keeps the dust bunnies out of the house.
