For a more budget-friendly option, the Homedics SoundSleep White Noise Sound Machine will lull you to sweet dreams for just under $20. It offers six different sounds: white noise, thunder, ocean, rain, summer night, and brook. 

This noise machine has three auto-timer options so the sounds stop at 15, 30, or 60 minutes, depending on how long it takes you to fall asleep.
