P.R.
We have the Summer Infant one ($170) and it is our favorite product! It is particularly helpful if you have a 2 story home. It is also super portable...small enough to toss in the diaper bag if you need to take it with you somewhere. Battery life is pretty good. I would charge it daily for a few hours so it can be portable. The sound quality is wonderful. You can hear the baby breathe and can even see their chest moving. Yes, there is periodic static, but we've found the best way to alleviate it is to keep the handset away from the phones, cells, remotes, etc. I've read about the horror stories about where people can see other babies, etc. but we have not experienced that. Don't really know about what privacy precautions to take, but just be sure to turn off the camera when not needed. They also have one in pink that I've seen lately (not sure what you're having, but it may be fun for a girl!)
