If the other one that you were looking at is made by Steel Horse with the separate monitor that is not attached to the VCR unit, stay away from it. The Rampage (Audiovox) is a much better VCR for rhe price. The Steel Horse has tiny speakers that are no bigger than headset speakers. We have no trouble hearing the sound over the road noise with the Audiovox. the Audiovox has several picture adjustments that the other one does not have such as contrast and color. The Audiovox does hang between the seats but the instructions also show that it can be placed on a seat and attached to a safety belt.
$250 is a great price, we paid $299 over the summer.
Another alternative is a portable DVD player but they are more expensive and you would have to hold it in your lap to watch it.
