As always there is more than one way of dealing with an issue. Unless I have specific need otherwise, I personally like dealing with cursors since they are highly manageable and provide automatic failsafe for unwanted table changes. Updating the summed field is no problem using events and might give more control in given circumstances. Always good to see more than one way of dealing with things.
