家電維修或換新? ... 請大家各書己見

家電維修或換新是個問題。尤其是當你的出租房的芳齡超過十年。網上傳說有許多辦
法來決定:修，還是換新。一個比較時尚的辦法是 50% Rule:  "If an appliance
is more than 50% through its lifespan, and if the cost of one repair is
more than 50% of the cost of buying new, then you should replace rather
than repair."
舉例說，一個洗衣機大約用了十年，是請人修，還是換新的? 請大家各書己見。
