In my experience, its just easier/cheaper to buy cheap but decent quality umbrellas and not have to worry about them. I think probably the last 3 umbrellas I bought were bought not to replace a broken umbrella, but to replace an umbrella that was left somewhere. I've got a Lewis N. Clark umbrella that's lasted me the past 5 years and somehow has managed to not get lost or broken. I don't tend to go outside when its super windy, so that's probably helped its longevity. They're about $10-15 on Amazon generally.
