Siggi, You will find that flex boards are more expensive than rigid boards whether or not they bend during their operating life. The once only bend is normally referred to as a static bend. If you're only going to make a bend once it allows you to do two things. First you can make the bend much sharper second you can use a multi layer board - it's generally regarded as bad practice to subject a multi layer board to fatigue loading.
