Some great photos in this thread.
I buy what I like and shoot what I buy. I have no way to display antiques though I think it would be cool to own some nice original 1800s Winchesters as they are truly wonderful pieces of machined art. For me I guess I like the repros. You can drill and tap them for sights, or not; you can strip and refinish them, or not. Just doesn't matter what you do as you're not effecting their value so you can do with them as you want. The more fun I can have with my stuff the better.
