Another easy way to do natural peanut butter is to store it up side down. That way the oil is in the bottom and its easier to stir. That's for them what don't like their peanut butter cold. Just make sure the lid is on VEY tight before you do this! Voice of experience talking here.
I don't like having to stir it each time!
If I had something that made stirring it easy, I might. Otherwise...it's easier just to stick it in the fridge.
