I have some of the ACW and South America ironclads from Spithead,
Very nice detail!
Phil did produce the Lissa range previously, I think he has to do something with the molds, update them, clean them up, something, but we can't get the Lissa ships just yet. He plans on molding some more in the future.
I have seen some other 1/1200 ships from that era, it depends on how much you want to spend for them. Some are more collectible ones say from Navis or Hai, which cost quite a bit per ship.
