If you hurry over to Amazon you can grab a Angelcare Baby Movement and Sound Monitor, Blue for only $6.59!
That is a ASOME deal. This is normally $129.99. I am not sure how long it will last at that price, so if you want it I would hurry.
These are the product features.
“1 parents unit 1 nursery unit 1 charging base 1 sensor pad 2 AC adapters 4 NiMH rechargeable batteries
Nursery unit has a soft nightlight and room thermometer
The sound monitor operates on the 927 MHz frequency so there is no interference from 2.4 GHz equipment”
