For a "general purpose" shotgun ...I think you're making a smart choice.
There are about 29 different models of the Citori these days...and the Lightning is their "field" grade gun...the price might be a little high / but it looks to be in very good shape from the photos - and all of the Browning Citori models hold their value very well.
Today's current Lightning model list for $ 1,990 ....and in many areas they will sell new in box for around $ 1,800.
Its a gun, if you take good care of it, that will easily last thru 500,000 shells and live on in your family for many generations ( I have a number of Citori models that are well over 500,000 shells with no issues at all ).
If down the road -- you want to look for a dedicated "Trap" gun look at the Citori XT Trap, 12ga, 32" barrels...they're very solid guns as well...a little too long and too heavy for general purpose ( like Skeet, Sporting Clays, 5 Stand...).
