Reuven borrowed Shimon’s old but sturdy shtender. Reuven broke the shtender and it is no longer usable. The old shtender was worth $10 but there is no market for old shtenders. If Shimon wants to buy a shtender he would have to buy a new one and spend $30. What does Reuven owe Shimon? The value of what he broke? Or the replacement cost to Shimon?
