What are you going to be using the revolver for? If it is mainly going to be for shooting at the range, plinking and hunting, the double action feature isn't really gaining you anything as shooting a revolver double action makes for a long trigger pull and it is harder to keep on target that way, I almost always cock my double action before shooting to attain the best accuracy, now if you are planning on carrying it for self defense, which a larger 22 revolver won't be so easy to conceal, then the double action makes sense because you may not have time to cock the hammer before the bad guy can get at you. My preference in these guns lies with the Ruger single six, single ten (though they are LR only, and I don't like the fiberoptic sights), or the little bearcat(also long rifle and no adjustable sights) however all 3 of these are single action. One issue I have with the convertible revolvers is that everyone I have ever fired seems to like the Magnum round much better than the long rifle accuracy wise, I don't like to shoot the Magnums as they are expensive and loud as hell out of a revolver. If you shoot mags be sure to have ear protection because you WILL damage your hearing with them.
