I was going to ask if anyone knew of a good cheap source of canned air( I just hate that I can walk into a dollar store and get 16 oz can of spray wax, window cleaner, bubbly bathrooom stuff etc. for a buck, but am charged $6-$9 for 10oz can of well AIR. Well I know may the propellant is more costly than wax and quite a bit less propellant. But still.... My box is waaaay due for a good cleaning so I was looking for the best price on canned air to replace the one I am sure to use up. I came across a 2 wire a/c blower for sale w/ excellent reviews, mfr link https://www.metrovacworld.com/DataVac_Electric_Duster Has any one tried this option ??
