Additional Performance Profilers

I've gotten a few questions about other profiling tools to use when profiling WPF applications.  I'm putting this on my 'things-to-do' list, but if anyone has experience with using other profilers against WPF, I'd love to hear about it.  In the meantime you can checkout this Wikipedia article on Performance Analysis, which has a list of 10+ profilers that I plan to try out at some point.
