If you have a way to use zwave devices, I have the GoControl GD00Z-4 which flashes a light and beeps for 3 seconds before opening or closing the garage door. Only catch is it only does the alert/delay if triggered over zwave, so pushing a normal rf or wired button wouldn't make it go off.
It's actually the only thing I don't like about it because it cannot be disabled.
