Considering you can get a new one for 229 I'd say 200 would be top dollar for one NIB as long as it was made since 2000 but me personally, if I couldn't get it for 175 or less I'd go probably with a brand new one.
Not to hijack the thread, but how about a Richland Arms New Army in SS? I am very new to black powder, but saw one of these on auction and put a bid in on impulse.
