Baby Monitors?

I think I remember someone mentioning a baby monitor tha has two base units so you can have it in two kids rooms at the same time. Does anyone know what brand it is? I have a Fisher Price one in Maya's room atm as she is down the back of the house, but will need one for the twins room as their apnoea monitors aren't loud enough to wake me up in the next room without the sound monitor.

Aha! Thank you! I wanted to make sure I wasn't imagining things!
