Farmer,
I started out with a large Senco framer in the early 80's that i bought in a pawn shop for $50. I built a house, then did fences and decks as a side job. Had to have the O rings done several times but really got a lot of use out of the thing. I ended up buying a PC framer 4-5 years ago because the nails jus got too expensive. The PC nails are stocked at Home Desperate and are half the price of the old clipped Senco's. The nice thing is the lighter weight of the PC...it is noticable when you put 6 nails to a picket and nail a thousand pickets! The ole Senco gave my "tennis elbow" fits, due to it's heavy weight. I have also added a Senco finish nailer, PC brad nailer and a Paslode roofing stapler. The stapler is also great for doing field fence. All in all the PC has held up great, and hasn't need any O rings (yet...knock on wood).
They all beat a hammer hands down. BTW, before the Senco, i rented a Hitachi Framer....the thing was so fast i put a 3" nail thu my left index finger.....Be CAREFULL when nailing something that is not against something firm. The first nail can hit a free standing boad such as a stake for a string line and bounce the board off the nose of the gun. When it comes back into contact with the nose and your trigger finger is still on the trigger, you will shoot another nail....most likely somwhere other than when you intended. Also be carefull when toe-nailing...they can riccocet off and fly wild. EYE protection is a real good idea /forums/images/graemlins/wink.gif
One more thing, keep your kids away from you when using the gun. We have a habit of keeping the finger on the trigger when doing multiple nailings, and you never know when a young'un is going to walk up behind you and possibly bump into the nose of the gun.
.....ok, i'm stepping down from the soap box /forums/images/graemlins/grin.gif
