Because I grew up to be frugal, resourceful etc., I have been dealing with 40+ year old lever grease gun. After reading the start of this thread, I decided to buy a new pistol grip. Should have done it years ago, just for the convenience of making it a two hand operation instead of two hands and a thigh, chest, whatever. I don't like getting greasy, but it comes with the territory. That's what rags, soap and water are for.
I do wish there were grease fittings on my zero turn spindles, although I never had a lawnmower spindle fail after 10+ years...
