For reduced recoil, gas operated autos are your way to go. Most companies have gas regulated semis, but stay away from anythingBenelli, Franchi I-12's, and the Stoeger Model 2000. These are all inertia operated, and will pound your shoulder.

Just about anything else should do fine.

And not to plug my ad on your post, but I am selling my Remington 11-87 Super Mag on the classified section. I've actually tested the 11-87's kick compared to the 870 pump with various loads, andthe 11-87significantly reduced it. Feel free to check it out if you're interested.

Sorry for the promo, good luck on the decision though.
