blades out with hand tools? We put off the purchase of an air tank for most of last year, this year we broke down and got a Porter/Cable tank, gun, hoses and various fittings. $270.00. Was the best purchase of the year so far. We change out much more often and with little effort. The toughest part is bleeding the tank after each time! If you've been thinking of getting one for the shop, no need to wait, it will be worth it. Just thought I would pass that on.
