Query: Not a good buy.

If your looking for a cordless nailgun that costs more to operate in 2 months than you paid, then you've found your gun.I got a average of 200 nails per gas cylinder (they claim 1200) at a cost of $13 a pop. I actually went through four cylinders in one day. I have two paslode framing guns and thought i would try an Hitachi.I am a builder an use these guns all the time. But this Hitachi has been in the repair shop for two months. I think im going to leave it there.
