Have I got good news for you! http://www.thesleepwatch.com/ http://www.thesleepwatch.com/ It's $150, takes a CR2032 battery that lasts 12 months; $50 if you can live without the vibration. I used one for a couple of years, before I had a kid (who wakes me up by jumping on the bed). I really liked it. I woke up feeling noticeably more refreshed. It's not life changing, but it's quite nice. (Despite its name, it's not really all that good for tracking your sleep, because it has no wireless support, but the alarm feature is all I need anyway. Get a Fitbit if you want wireless tracking, I guess.)
