Here is a product review for the Sony Baby Call Nursery Monitor. We have been using this monitor for 18 months and have loved it!
Here are the specifics:
-900MHz monitor has five sound-sensor activity lights, out-of-range indicator and low-battery warning keep you informed of your baby's actions and the status of your equipment
-A belt-clip is included for both receivers, keeping your hands free for other activities
-Receivers are water-resistant for use in the bathroom or kitchen
-27 channels to greatly minimize interference
-Built-in rechargeable battery receiver
-Voice activation mode: eliminates most extraneous background noise for clearer transmission
I found this monitor available at Target, Walmart, and Amazon all for under $32. That's a great price for this quality monitor.
