The K110D has 3200. Whether it's that "real" 3200 versus boosted, or whatever phrasing I've seen about real ISO versus pushed numbers, I don't really know, but the options are 200 to 3200.
The combination of 3200 and my SMC Pentax-M 50mm f1.7 lets me get away with some REALLY dark shots that really push the limits of my ability to hand hold and even to manually focus through the viewfinder and still not be unacceptably noisy.

This one was shot in a bar lit by two 60 watt bulbs in recessed hangers and the modeling lights off a different photographer's soft boxes. It was DARK in there.
