C++ Logging Lib on VS2005 - Log4CPP or Boost or Pantheios or what

Hi All,
I'm lookign for stable, simple, easy to use logging lib and have been exploring Log4CPP , Boost, Pantheios etc...but I'm lost :(

I have multithreaded VC++ application and it's using other static libraries as weIl as dynamic and I want all logging to go to one file in the system. So I want to have a logging lib as a separate static lib or DLL so all components would easily integrate. I have been surfing around option like Log4CPP etc but really can't make any decision right now. I would highly appreciate anyones comment.

thanks.
