The trapping of errors is only expensive when there's an error to be handled. Otherwise, it's cheap - often cheaper than the alternative of whatever conditional testing you'd otherwise do. And, there's no reason why you can't think of exceptions as just one more part of an API, just another sort of message passed between objects.
