I don't know about anyone else, but I really liked the DC Universe Infinite Heroes line. Here is a few shot of Batman from that line. I know that in addition to this dark blue version with the large bat logo there was also a light blue version with the yellow and black oval logo on his chest. These guys are around 3" tall and feature about 9 points of articulation.
Batman's cape is very stiff and kind of limits what you can do with him. For their small size many of the figures have really nice paint details.
