Cowboy,
Yes, I've shot my friend's RBL 20g, I visited the factory to see the manufacturing and  took an hour long tour personally hosted by Tony himself for just two of us.  I have no beef with them, but don't think it's exactly what I'm looking for either.  I prefer a Parker repro for about the same money as I think it's a better made gun, both asthetically and execution wise (from a manufacturing quality perspective).  
Frankly, I think CSM would do well in offering a Fox 20/16 Sterlingworth version of their Fox line, for a common man's price that was competitive to the RBL line.  No options, just a couple versions, straight and pistol.  No wood choice, no ordering, just off the shelf.
