One way or the other

Normal sudoku rules apply. Exclusivity: No digit from 1 to 9 may appear in both a circle and a killer cage. In other words: If a digit appears in a circle, it may not be contained in any killer cage and vice versa. Digits in a cage sum to the clue in the top left. Digits on an arrow sum to the digit in the circle from which the arrow emerges. A circled digit indicates exactly how many circles contain that digit. (Note that this also includes circles with emerging arrows.)
