Air compressor help

I started out with a compressor with the same ratings as the one your looking at and I hated it. It wouldn't keep up with hardly anything I tried to use on it except inflating tires. Get something with at least 10 cfm at 90 lbs. and at least a 40 gallon tank if you plan on spray painting or using a die grinder much or really putting the impact to use. I now have a 60 gallon Devilbiss that I bought at Rural King for $369 about 3 yrs. ago. It's rated at 11 cfm at 90 lbs. and even with that when I port heads the die grinder or DA sander will kill it in 25-30 minutes of continual use then I have to take a 5-10 minute break to let it catch up.
