I still think a good solid used Citori XT ...with 32" barrels....is where you're going to find the best gun for your budget in the short run......and the easiest Trap gun to sell down the road ...
( every Trap shooter I know ....moves on from their 1st guns ! ).....not that the XT can't be a very good long term gun, I think it is ......but its far from being in the arena of the fanciest with Krieghoff, Kolar, Perazi, Blaser, etc...
I don't really lust after any new shotguns anymore ...but my buddy has a Krieghoff KX5 single ...with an upgraded stock on it....that's so pretty, it'll almost stop your heart.../ but appearance doesn't break targets either.

If you're shooting 10 lines of Trap a week for practice that's about $ 150 a week or $ 1,800 a year.../ so the cost of a new gun is the least expensive part of this game, by far !! So it gets pretty easy to justify, at least in my mind, on spending $ 5K - $ 10 on a Trap gun that you really like !!

A pair of XT's that I have...both in 32"...one with an upgraded stock and a Gra Coil I bought used for around $ 2,500 about 8 or 10 yrs ago...and still a solid gun ..
