OK, I've read and attempted all of the tutorials I can find on being able to debug a locally installed Drupal 6 instance.
I'm on Windows, 32-bit. I have access to Eclipse (obviously) as well as Visual Studio 2005/2008.
I've yet to be able to get any of the Eclipse options (XDebug, Zend, etc.) working to be able to step through code, inspect variables, etc.
I've heard good things about VS.PHP, but haven't committed to the $100 or whatever it is.
Can some of your PHP/Drupal gurus out there tell me the best, simplest, most reliable way to debug Drupal and PHP on the Windows platform?
