As they look good I have also heard some stories that one should keep in mind. I heard that the warrenty on the DSD are Nil and they have had issues with shipping that the company would not stand behind. Now I'm not saying this is true but rather only heard.
The new Zink decoy is every bit as good and is also much lower in price. I'm also like JW and like the Bobblin head too but that company has gone into the ground, so when mine is gone so I bought the zink feeder for a back up
