Minimum Air Compressor

agree with above. i had an oil-less pos from home depot, something like this:

which left me waiting for air quite a bit. you can run a DA, just not for long. It was however OK for painting and airing up tires :)

Now I have an older version of [ame="http://www.amazon.com/Campbell-Hausfeld-VT6271-Oil-Lubricated-Horizontal/dp/B00081AKME"]Amazon.com: Campbell Hausfeld VT6271 26 Gallon ASME Oil-Lubricated 240V Horizontal Air Compressor: Home Improvement[/ame]

I am now never left waiting for air, the recovery is amazing with the 220 cast iron pump ( and real horsepower)

One other thing, those oil-less things have a high pitched sound that is very annoying!
