I don't care for pure single-actions either, but that's the way I shoot double-action .22 revolvers. A modern S&W would be fine and they may outshoot the older ones, but I've had very good results with a 17, an 18, an old Model Colt Trooper 4", and a Colt Officer's Model Match 6". All these guns shoot equally well, but I haven't bought a handgun in years and am not up on current costs and availability.
You can go with lesser guns than Colt and S&W and spend less but the latter will old value well and always be more desirable at sale or trade time. That might not be true of the others even if they turn out to be excellent guns. You don't want to buy something too soon then wish you had held out for something better.
