I would definitely get the Wrangler over the Single-Six (having had both, and still having the Wrangler)-advantages of the Wrangler include:
1. A built-in exercise function; opening the loading gate can develop muscles you never realized you had in your fingers and hand
2. Increased stopping power; rather than launching the tiny .22 projectiles point-forward, where they're smallest, it launches them sideways, increasing potential stopping power by 2-300%
3. A child-like sense of surprise and wonder whenever you shoot; yes, you aimed at that thing over there, but imagine the delighted surprise you'll have when you actually hit that thing way over THERE
4. It's CHEAP; you can revel in the feeling of economic and financial acumen you've demonstrated by only spending $200 on a completely non-functional firearm, rather than $600 on one that just boringly functions and hits as expected-you're the next Warren Buffet!
5. It's a gunsmithing trade school in one gun; you'll have hours of fun trying to decide how to make the bullets come out point-forward (if you're willing to give up that increased stopping power), how Ruger managed to make three of the chambers slightly large, one correct and two slightly tight (think of the tool changes needed to do that-above and beyond!), why the cylinder gap varies by 50% from one side of the cylinder to another and other fun projects. When you're done, you'll be nearly ready to build your own SA revolver from soup cans and water pipe-similar to what Ruger did
6. The fun of explaining to people on the internet that, 'for the money' it's really a great value
