Just to help you out in your purchase. There is no bow that is twice the bow of the new Stinger 3g... new or old. It will shoot as good as you can... world champion or novice... after owning it a week I cannot believe how accurate it is.
The biggest factor to buying it new was the lifetime warranty... I take care of my stuff so I probably won't need it, but you never know. You can pay as much, or little, for a bow as you want, but I think the Stinger offers great value for the price. I am totally satisfied with it.
Hope this helps some,
Mark
