The reusable cartridge-types aren't worth it. The blasts aren't as powerful as from a warm can of canned air. You'll end up going through 3 cartridges for the equivalent of one good long blast from a regular 10 or 12oz can and the cartridges aren't normal-sized CO2 cartridges so you're stuck paying their price for their cartridges instead of being able to shop sales.
I usually pick up a couple of 3-packs of 12oz cans from Microcenter B&M when they've got them on sale. The price often drops to $8 dollars or less. 'Got to keep an eye on their monthly circulars to catch it. Regular price is $10 bucks for a 3-pack of 10oz dusters.
Sometimes Staples has a 10oz can on sale for $3 dollars or a pair for $7 dollars. Again, 'got to watch the circulars to catch it.
