I own the ultimate decoy bag. It's a little expensive, but I really like it. It's my favorite decoy bag because of the straps and the spot to carry my gun.
The one thing I don't like (but it's easily fixable) is the slider that closes the bag at the top is virtually worthless. You need to get a better slide or tie it off if you want to make sure it stays closed and all your decoys remain inside.
I don't think I would get it if I didn't need to carry my dekes very far. It's all a matter of comfort.
Also, if you don't need one to carry your gun, I think the less expensive one would work or Avery has a decoy back with the heavy duty straps.
