The old adage goes something like this," the attraction of low price wears quickly off with the low quality".
The Ruger Bisley .22LR has a long barrel and is pretty nice, but I dont know if it comes in a swap cylinder set.
The grip doesnt suit everyone, in that case go with the Single Six, which can come with both cylinders. The 22 Mag will rarely be used by most, still, it adds to the 'package'.
If you want something a bit more 'vintage' look for the real Colt's New Frontier 22/22M set; it came in several barrel lengths and the two I know of are every bit the 22 version of the Flattop Target in that '7/8ths' size (BTW, mine isnt for sale). The earlier versions from Colt's in the Frontier Scout, etc. had a 'zamac' frame and fixed sights, not near as nice as the one I mentioned above and mine wasnt very accurate (OK for cans). They had a steel frame version of the Scout in the Peacemaker(?IIRC) that I never got to try.
As for the imports, IMHO with the dollar value down the cost of them is about what you can find a nice, used USA made revolver, so get the real deal.
