I got lucky and found a new in box Franchi 620, for my daughter Fairy light with light recoil, and flawless operation. Everyone that shoots that gun loves it.
We recently purchased a Remington 1187 compact, in 20 gauge, for my son. So far, it has functioned well, and he shoots it pretty well.
Another gun to consider would be a Winchester SX4, in 20 gauge. It is a recent offering by Winchester.
Turkish made Tristars, Weatherbys, and Mossbergs get pretty good reviews. You may want to check those out as well.
