WIth the second baby there are a lot of things we are re-using, but some things we had to double-up on, like a new monitor. Creature of habit that I am, at first I wanted one just like the old one, because it seemed to work pretty well at long distances and it operated in the 900 MHz band (between the cordless phones and WiFi the 2.4 GHz band was getting pretty crowded). But the old one wasn't available any more, so I had to settle on the new model, and I'm really glad I did.
There are a couple of enhancements to it, first and foremost being the fact that the receivers are rechargeable. With all the AAAs I was feeding into the old one, this new feature is great. Plus, it's got an LED screen telling how much battery life is left, the signal strength and what channel you're on. It will even beep at you if it isn't receiving any signal at all, or if the battery is dying.
It doesn't rumble like the old one did, but I'll gladly trade that in for a battery that recharges. It's not like I've got a lawn to mow while the baby is sleeping.
