I have a Homemedics sound machine for my son that is great! It doesn't have a projector, just makes noise, but I love it because it is so small and portable. It even takes batteries OR plugs into the wall! I have taken it on several trips with us and I don't think I would ever get anything different (one of the hotels we stayed at didn't have a plug that was accessible, so we were able to get batteries and run it anyway!). It truly is so convenient. It has a number of different sounds and a timer if you want it to turn itself off. I got it at Bed, Bath and Beyond if I remember right. It doesn't have a night light, but I always throw one of those in a bag when we travel anyway. I hope this was helpful.
