Honestly, for eggs I've found this to work a treat:
Take a small pot with a lid, add 1cm (1/2 inch) of water, put eggs in, throw on cooker (up to boiling very quickly). 5 minutes later, soft boiled, 7+ minutes for hard boiled.
Usually find 5 minutes is just enough time to make toast and a coffee. ;)
