Browning Citori.
I've never ever ever ever ever regretted buying this gun. I used a Remington 11-87 which is my jack of all trades gun (more like a King...but not quite an ace) for everything from upland birds, wetland birds, clay birds on trap & skeet ranges, deer, turkey and the senseless slaughter of the devil...coyotes.
Worked great until I entered my first tournament. No big deal except I entered 16 and 27 yard distances with 100 birds each. Then shot an Annie Oakley after that and the next day I couldn't eat, smile or hardly talk because of the pain on the right side of my face. At that point I began shopping for a target gun that was comfortable to shoot. My uncle owned a Browning Citori and offered it to me to try out next I was in town. I took him up on that and though his was $2000+ new I found a different model in the local Gander Mountain store which had been very gently used and in quite good condition for $700. No case or anything so I built my own wood case, stained it and put in some nice padding and bought a couple yards of this nifty shiny fabric to put inside. I don't remember what it's called but its very soft and looks quite nice.
Anyways...I say you can't go wrong with Browning. If you're ever shopping for a non-target shotgun, (Belgian) Browning Auto-5. Again, I am jealous of my uncle!
