Oh man, that's so true. I mean, it's like we all learn this lesson with different stuff. You go cheap on something you really depend on, and it lets you down exactly when you need it most. I had the same thing happen with a backpack once, straps just gave out on a hike. Now I see it everywhere, like with tools or even winter coats. It's not about being fancy, it's about not having your stuff fall apart at the worst possible time.
Ever try to fix a cheap zipper that busts right before a trip? I keep a basic sewing kit and some heavy duty thread for quick repairs on gear. It won't make junk last forever, but it can save you in a pinch.
