aircat?

That really caught me off-guard!

If anything the air tool is more green given the compressor doesn't have lithum batteries and the compressor and tool have EXTREMELY long lives usually.

I would buy Astro Pneumatic. So far so good on everything I have from them and the price is also very reasonable.
Like I said, I'm no liberal tree hugger. I have and love my air tools, but with 3 acres, I can't have enough hose to reach the edges of our property. My DeWalts are better than hand tools for repairing fences, sheds, trees, and other things that require upkeep. They are also invaluable for removing parts from cars and trucks in the bone yards. I also have several hydraulic tools, like my Bendpak 2 post lift, and big lug crimpers.Most every tool has a use, and I wouldn't part with any of them. I was only offering a suggestion, not making a political stand.
