I have a Senco 25XP which I really like. Other
than jamming, here's a few things to consider:
*when you run out of brads, does the thing continue to
"dry fire", punching holes with no nails, or does it stop
and force you to reload?
*does it require lubrication? If so, in general you will
end up with some oil mist on the work.
At least when I got it, the Senco brad nailer was made in the US.
Ditto my Senco 15 ga finish nailer. I was a little bummed
when I found that my Senco 23ga pin nailer was made in Taiwan,
but it works pretty well.
There are many people in this newsgroup who swear by Harbor
Freight, and if your thing is getting something functional at
the lowest possible price, that is the way to go. Personally, i like
the feel of a well-made tool and I want it to last longer than I will.
In the nailer department, I go for Senco.
