I've seen prices up to $600+ in my travels. Actually I think the stainless versions have been a bit less... All factors considered $400 is a very good deal IMO.
I've hunted with my 10.5" blued Blackhawk for years, usually from a rest in an elevated stand. The velocity and sight radius advantages, albeit minor, give me an extra confidence when that 10-point is out there jusssttt a little further. The long Ruger will shoot about anything I can stuff into the chambers, and shoots it all very well.
I rigged a sling on my scoped 44M to carry it under my shoulder when walking. UM made a decent bandolier-type holster that works great also if you're into open sights.
After pondering value a minute, I wouldn't take $550 for my blue gun. Go grab that piece if its still there!
