We have one (2.4G), I absolutely couldn't live without it. I was sick of the static on our (expensive) audio one and I was sick of going up and down the stairs to check on DS. The one we have is Samico (the blue and white one), we bought it January 2010 I think and no problems yet (may need to be charged more often just lately). The price was about $120 and we got it on ebay. I don't know why everyone doesn't have one, the sound and picture are great!
