Magic Lantern has DotTune. Takes 1 minute / lens or 2 minutes / zoom lens.
With that said I prefer to let the Canon service center fixes bad autofocus. Microadjustment is in my world only a temporary solution. In Japan a calibration costs around 10$. In Sweden (Europe?) 150$. Somebody living in U.S.A maybe can tell what it costs there.
