I love our Summer Infant brand video monitor. We have the one that looks like a small tv, not the one with the handheld monitor. I liked the bigger screen and didnt have a big enough house to be worth the extra for the handheld. I still use a cheap sound-only monitor for the living area and keep the video next to my bed.
The thing about video monitors is that they will work differently for everyone depending on the layout of your house and what is around you that might cause interference. So you might see one at a friends house that seems great, but the same one at yours could be just static. Keep your receipt that way if the one you choose doesn't work great, you can try a different one. And if it seems to staticky in one spot, try moving both pieces around a little- the part in baby's room and the monitor in yours. But I really like ours. It was right around $100. They carry it at target, walmart and babies r us.
