PFFT to that rude woman.

We have a Fisher-Price one. It's simple, but really sensitive. Jazz is asleep right now (OMG praise the universe!) and when she rolls over I can hear her blankets rustle through the monitor. And its about 2m away from her! It has a night light on the microphone part which is good, gives just enough light to be able to see but not too much to make the room bright.

We did have a problem in our old house with interferance on one channel, but nothing in the new house. Not sure what the problem was, but just thought you'd like to know.
