Is there a Per-Mesh-Profiler somewhere?

Is there a tool available, either built into Unity or from a third party, that allows me to see what time every single mesh takes to render? I have a very extensive scene with a few dozen meshes and one or more meshes are killing my frame rate. Switching every single mesh on and off and observing the difference in the render stats window is not really an option, because the render stats are a bit hard to read and not perfectly accurate. I'd appreciate a hint or two.

nVidia's PerfHud helped me out in the end. I was not able to find anything better. ATI also has a tool for this, it's called GPU PerfStudio, but I wasn't able to get it to work with Unity for some reason. PerfStudio looks a lot more sophisticated and useful though than PerfHud - at least in theory. But PerfHud did the job for me.

The only thing better than the statistics window is the Unity Profiler, but that requires Unity Pro and is not free.
