Query: Battery Eating Machine

We bought two video now Colors, and a video Now Jr. for our kids, thinking it would be fun for the car. However with standard alkaline batteries not one of them lasts for more than 5 minutes. I spent money on the more expensive (M3) batteries, and they seem to last longer. However at $9 a pack that seems a bit pricey, even the rechargables don't hold up well in the player.
