is it 400 for just the bow, or 400 for everything? Because if you are going to hunt, you will need things like a site, quiver, etc.
If it's 400 for just the bow, check out the PSE Brute X. It's right under that & a heck of a bow.
If you've got 400 for the whole package, you should look into the PSE Stinger 3 G. Look for things on amazon that say RTH or RTS which means the bow is ready to hunt or ready to shoot as soon as you get it. There's tons of options out there.
