The Ruger 1911 would probably be my choice if I had to pick from your list. A Ruger Vaquero would be nice too if I could decide on caliber.
I know this wasn't in your poll but someone else mentioned it so I'll second it. A Smith and Wesson 19 would be a great choice. I've been trying to find either a 19 or 66 at a decent price for some time now.
