Quality grease gun ?

where can one buy a good old style full size grease gun? I had a good one from back in the day, where you pulled the plunger back and kicked it to the side to hold it. the new one I bought at autozone or advance has a lame little lever that broke cuz I tried to use it when cold
here on the farm, we use a TON of grease. The best grease gun we have found believe it or not is that of the tractor supply brand. Had a pair of them now for about 10 years and they still work flawless. Plus both of them are designed to accept either the prepacked tubes or with a simple flip of the push rod, can accept bulk, user filled grease as well.
