I use a saucepan of water and bring the water to a rolling boil.
I crack the eggs into a whiskey glass, and then slide the eggs into the water.
I turn the heat off and cover the pan when the water settles, and set the timer for 3 minutes and 45 seconds, sometimes four minutes.

Works quite well - most of the time. It's important to keep my wife out of the kitchen while I'm doing this. She tends not to get out of the way when I need to get a spoon or fetch the toast or whatnot. We've had some disagreements about this. ;-)
