My 111c slow speeds work perfectly well, and I use them a fair bit now (church interiors and the like).
The 111c will take a perfectly sharp picture at 1/20th handheld if you're a steady shooter. Cheaper than a fast lens!
It comes down to getting your camera from a reputable source who, if he/she has not given it a CLA, has at least checked to see that everything is working as it should. The 111c is pretty tough.
