I'd look for a Dan Wesson. I'd rate it above any of the above, and decent examples are often available between 3-400. Plus you can add additional barrels later.
Good suggestion, the Dan Wessons are a great value. I don't know if I would rate them above the Security Six but it is on par with it.
Maybe if you want blues get a Dan Wesson. If you want stainless get a Ruger Six series
