Ours is a Lorex, we got it off Amazon and I really liked it. Good sound and picture quality, plus the battery life was around 6 hours without charging. Avoid Safety First, we initially had one from them but it broke after around 3 months. They sent a replacement that came out of the box broken so we opted for a full refund and then got the Lorex. We have a 2 story house, so a monitor was a must especially at night and I really liked being able to see what was going on. Video monitors aren't a necessity, but it was worth it for us. Ours had 2 way audio, so we could talk to him over it too, it came in handy when he grew up a bit and would wake up. I could tell him it wasn't time to get up yet and he'd lay back down. Totally worth the $$ for us!
