Instead of one of these dedicated baby monitors, I ended up getting a Foscam FI8910W IP Camera.
This camera was dirt cheap compared to the dedicated video monitors, and has served us very well.
One of the best features of using an IP Camera for your baby monitor is that you're not limited to viewing the camera with a single viewing device - like you are with a CCTV-like baby monitor system. I use IP Cam Viewer Pro on my Android phone and tablet as well as on my wife's iPhone and iPad. Get IP Cam Viewer Pro here for Android or iOS.
If you know how to configure your router to allow web traffic to the camera from outside your home network, you can even pull up the baby monitor if you're not at home. The only downside to the Foscam FI8910W is that it does not provide a secure web interface - so if you do allow external access through your router - make sure you use complex user passwords and change your passwords frequently.
Foscam does have an updated version of their IP Camera that is "better" than mine. That model is the Foscam FI9821W V2.
This updated version does alleviate the security concern I mentioned above by implementing a secure web server (traffic goes over HTTPS). However, if you read the reviews on Amazon, the 9821W doesn't get nearly as good reviews as the older 8910 did. So it's up to you whether you want to chance it on the newer model.
Hopefully this helps provide an alternative to purchasing the expensive baby monitor systems that you'll encounter at the big box baby stores like Babies R Us!
