After my last cheapo compressor died in a horrible texturing accident (after five years of faithful service, may it rest in peace at the landfill), I felt like it was time for the real deal. Things that drove me to pick this model in particular:
I also like the look, the wheels, the relatively quiet operation, 2 air outlets, the extendable handle, and the ball valve drain. DEWALT D55146
I am a diy'er, with little experience with air compressors before I bought this one. I researched between the porter cable, rigid and dewalt. I went with the dewalt because of the overall construction and quality of their other products. The pneumatic weels are great for moving it around in the garage and storing upright. The handle is solid and extends/retracts smoothly. The gauges are easy to read and the connectors are solidly built-in. The air drain release valve is a little difficult to reach, but a minor inconvenience. As for the power, I could see how if you were running two air nailers, the higher psi would be helpful when in reality for me it is bit overkill. It has a high scfm rating which I would like to test with a hvlp conversion gun for light spraying.
I first put this to use with a porter cable 16 gauge finish nail gun. I was installing Brazillian Walnut flooring (extremely hard), and used the nail gun to install the first row against the wall. After testing a few pieces, I installed the first row. Along with the test shots, the compressor fired 25 two inch finish nails before kicking in. With very little air coompressor experience, someone else might be able to tell you if this is good.
