IMHO... Forget all the frufra and turn back the clock, literally. Go buy a good windup. Proof against power failures. The nightly winding ritual can include resetting the time. Loud bells. No Snooze! Snooze just invites cancle cancle cancle. A single alarm gets one in the habit of being up at the same time every morning. Besides retro is sooo in style these days.
