So, what exactly is it about the SP101 that you don't like? If it is the weight, you mention in a subsequent post about a 2.5" S&W 66 (that you seem to have only decided against due to price) which is a K-frame, so both larger and heavier than the SP101. Also, as already mentioned, if you are soon going to a mobility scooter, how much does a couple ounces really matter? If it is the trigger, just about anything will be better. If it is the recoil, I'm not sure either option you are looking at would be better.
Personally, I wouldn't go with any of the guns you are considering. In small frame revolvers, my current choices are Colt and the Taurus 856. Sure, they are a hair wider, but I find the extra round to be comforting. For general carry I prefer the 3" new Colt King Cobra or Taurus Defender. For deeper concealment, the aluminum alloy (16oz) Taurus 856UL with a 2" barrel, though if you prefer steel the .38spl Colt Cobra and .357mag King Cobra as well as the 856 are all available with a 2" barrel. The Colts have some of the best triggers I've ever tried in a small frame modern production revolver. The Taurus isn't bad. Of course, the Colt King Cobra isn't cheap, but you may find a Cobra around the price (or just a bit higher) than what you are looking at, and you may be able to get two Taurus 856s for the same price as the Ruger.
Limited to just what you mentioned, I strongly prefer S&W over Ruger, so that is the way I'd go.
