Actually I have been a thunar user for years now, the simplicity and ergonomics of its features, the power of configuration (the point where konqueror fails), and the speed, are just things I cannot trade with other file managers. I have no issues with thunar anymore since the time I always run with Xfce4 DE.
The dependencies of thunar 1.4 are only few. You can download them all from here
including thunar 1.4 itself and build them from source.
If you need guidance in how to build it come back with specific question.
Hope that helps.
