I would rather spend $750 - $800 on a BFR and be done with it. Even if Ruger did come out with a 5 shot SBH or Bisley, the fit and finish would not be near as good as a BFR. And if you sent a Ruger off to a smith and paid for an action job, throat, recrown, recut forcing cone, remove endshake and set barrel/cylinder gap to minimun, freewheel cylinder, locking base pin and handlapped barrel, you would have more in it than a new BFR, which already has all these.
If it sounds like I am fed up with Ruger's poor quality in recent years, I am.
