Your budget may well determine your replacement.
In new guns, the closest thing to your beloved 3200 is likely the Kreighoff. Hold your breath for the price !
There are a number of decent Trap guns on the market. Perhaps a Browning 725 or Beretta 682 Gold E might fit the bill, and both are considerably less than the Kreighoff.
May be well worth your while to travel to a big shoot where you may be handle a large variety of guns ( most shoot competitors are quite good about letting you have a look at their guns)
& quite possibly shoot a round or two with a couple that seem to suit you.
