Welcome Swampman! Giving a nice Beretta to 3 kids is a nice gesture, but converting 3 grand into 3 new 20ga sxs's may be a tough job. No good new guns at the price point come to mind.

Your best bet will be to check the internet gun auctions on GunBroker or one of the others and buy 3 good 'used' guns, maybe Lefever nitro specials, or Fox Sterlingworths, LC Smith field grades, or even Stevens 311s (and pocket the change for shell money). Good luck with your search...Geo
