Biscuit - I am from the old school - I learned to shoot on a skeet field with a pump! The concept is this...once you can work a pump gun with ptroficiency, autos etc will be easy. Kinduv like learning to drive a manual transmission - from there you can drive anything!
I use an OU on the skeet field now - shorter dimensions allow for quick swings etc. For waterfowling I use pumps for reliability and durability but occaisionally use an auto. It is ironic that you are asking this question right now...I am in the process of looking for an OU to use hunting. I will not use the skeet gun in the field since duck guns do take a beating. I am looking hard at the Stoeger Condor. Low price but comes from a great background of manuafcturing. Franchi and Benelli are sisters of Stoeger. I have seen these pieces (msrp is $390) and they have good fit, a strong box and appear to have all I want in a duck piece. Wood and checkering or 'ok', but not exceptional.
One thing to keep in mind with a stack barrel is ---- no third shot, which can be critical on a wounded bird.
