There's about 4 main choices to go with the C&B revolvers:1866, Henry, 1873 and a Spencer. Within those groups, there's lots of choices of barrel lengths, stock styles, etc, especially with the '66 and '73. Most of the Winchester/Henry repros are made by Uberti, and marketed by a variety of companies. I don't know much about the Spencers, but they get a lot of style points, sort of makes up for the slowness.
