The problem with insurance is that you are gambling with your own money if you do not use it. If you paid several hundred $$$ for an electronic controller and you do not insure it, what happens if it gets lost, broken, or stolen? For a few dollars if anything happens to it, you at least get paid for your loss. If you fail to insure it you lose your investment completely. Sure it does not happen too often, but why take the chance just to save a few bucks. Postal insurance is relitively cheap in comparison to the losses you can suffer. Good luck with you decision and your shipment.
