Here's some real good advice--find out what you can get worked on locally. They do tend to have problems. My story--I found two at a local pawn shop. Same (excellent) condition, one a Stanley-Bostitch, the other Porter Cable. My friend who knows about such things advised me to go to the local dealer/repair shop and find out what they will work on. They said "anything Stanley_Bostitch--we can't get parts for the Porter Cable." I bought the S-B and before I built the first wall with it, some little plastic washer in the trigger mechanism broke and rendered it useless. For $25.00 it ceased to be useless and has worked flawlessly for [i]thousands[/i] of nails since. The PC would have stayed useless. Oh, I paid $115.00 for it. I also bought a S-B 15 ga. angle finish nailer on Ebay for $81.00--$92.00 delivered to my door. It has performed flawlessly. I do NOT know how they installed t & g pine boards with a damned punch in bygone decades. Whimpy insurance agents (me) NEED nail guns to get anything done. [BD]
