I really wanted a SxS, and I was leaning heavily towards a 28-gauge.
Then, a few years ago, another member here posted really pretty pictures of an older (middle 1950s, I think) Stevens 511 in 20 gauge.
I went out on a limb, asked him if it was for sale, and bought it when he said yes.
I forget exactly what I paid for it, but it was a fraction of what a CZ 20 or 28 gauge SxS would have cost me.
It is, without a doubt, my favorite shotgun.
