Pappy,
I make all my conversions except the Cimarron R&M conversions. I don't know anybody that is doing a true Richards conversion (.44 Colt, rebated frame, rebated cylinder etc;) except maybe Kenny Howell at R&D, and rather then pay his cost I learned to do them myself. Most of the so called Richards Conversions that you see are in .38 caliber (.38Long Colt, or .38 Special) on a .44 sized frame and conversion ring which Colt did not do. Not hard to do if you've got the right machinery, plus, it is a lot of fun to make your own cylinders and components.
