Baby monitor recommendations

[katiemomma]

Does anyone have some good recommendations? There are just so many to choose from! We've never used one before because we have always lived in one floor apartments/houses. But we just moved to a huge 2 story house and we cannot hear our son when he cries. I'm about to have another baby (any day now), so we definitely need to get some. Maybe even ones that monitor both the kiddos if possible?
So which ones have worked good for you ladies? (links would be great as well if you have them)

We have had the Fisher Price Sounds & Lights monitor for almost 5 years and it has worked great for our 3 kids, and I've loaned it to my sister for her son and it worked great for her too. The one we got only had one receiver, but now you can get it with either 1 or 2 receivers:

We have the MobiCam (http://www.getmobi.com/ultramobicam.html) monitors. I probably wouldn't have bought these myself (expensive), but they were a gift and they are amazing! We have two of the cameras and one receiver - you set each camera on a different channel and then you can switch channels on the monitor to see/hear each child. They pick up every little sound and the picture is amazing too (they even have a night vision mode).
