What do you moms think about used stuff?

I’m pregnant with my second and kind of looking into buying a used double stroller to save $ but then it kind of grosses me out. Still I think of if I were to sell my things, I’m a very clean person so giving or selling MY used baby things isn’t so weird to me. I spent a lot the first time around and would like to save this time. What do you moms think or are you buying used things?
