My daughter has a Sleeping Beauty (or Cinderella) Castle alarm clock - it plays princess music - not nature sounds, and has a night light that puts stars on the ceiling....she loves it - and it is easy for her to use, of course I have to set the alarm and stuff, but she knows how to work it....I think she was about 5 when she got it..... I am not sure how much it was because it was a gift, but I wouldn't think it would be more than $40.
