I have three O/U's: a Marlin Model 90 20 ga., a CZ Redhead 20 ga. and a Beretta 682 Gold E Sporting gun that also has a set of 28 ga. barrels. Forget the Marlin. It's great fun but long out of production and an antique. The CZ is a really nice piece and probably can't be beat for the money. As I recall, I think I paid about $800 for mine. The Beretta is a fairly high end gun with 32" barrels that I use for trap and sporting clays. It will go 250,000 rounds, then you can rebuild it for another million or so. It's meant to handle very high volume shooting, is a joy to handle and shoot, and it cost accordingly. The 28 ga. barrels are fun for skeet and dove shooting. I had a Browning 725 trap gun for a while and it was a little heavier than I like so I sold it. Beautiful gun, though. I think you can't go wrong in the sub-$2000 range with the Berettas or Brownings. Either are well built and will last a lifetime. Try both if you can, then buy the one that works best for you.
