If you want it really portable, and will use it on nothing more than a
finishing nailer, the little Senco is marvelous. Light, quiet, and rather
cute; but not much capacity. It took me 5 minutes to add 5 psi to a SUV
tire.

I have used HF and Dewalt nailers. The HF works okay, but just feels cheap;
the Dewalt is nicer. Now, whether that translates into product life or
whatever, I can't say.
