I was just going to suggest, Harbor Freight has Lincoln 12V powered grease guns. I wouldn't waste a dime on those smaller compressors. I use a heavy duty 80 gal Quincy in my garage and a light duty 80 gal DeVilbiss for the house. Compressors are like tractors. Once you buy one, you realize all the other things you can do with one, THEN realize how much bigger a one you should have bought in the first place. My place is rough and I cut down turf tires on my lawn tractor all the time. BC (before compressor) I had to jack it up, remove the tire and bring it to town. Now I drive it to the garage, fix it with a plug kit from Wal-Mart and blow it up myself - in less than five minutes I'm back out mowing. When it's dusty, I blow the radiator and air filters out. And yes, all the air tools including sand blaster. It goes on and on. Tractors though are a lot more fun!
