I am buying my son an alarm clock with sunrise light for x-mas. Does anyone have any suggestions as there are several brands and they seem different? He wants one with a radio. I guess you set the alarm and about half an hour before it goes off, a light comes on that gets brighter and brighter until the room is bright enough you think it is daylight, and it is easier to get up. I do not want one with a difficult/expensive bulb replacement---especially a bulb that is hard to find. Thanks for any help. I really need to order one today or tomorrow.
