I just configured Eclipse with PyDev latest version, but when I import external modules, neither code completion nor syntax highlighting works. How do I enable it?
Komodo Edit does a better synax highlighting, apparently. - But Ctrl+R doesnt run the program. 
I prefer a SciTE kind of editor with similar highlighting and fonts (aesthetics) and F5 working but with display of folder and files dynamically like Komodo Edit and a better code completion and vi emulation. Suggestions, please.
If I want to buy a Py IDE, Komodo or Wingware, which is better?-- Wrt syntax highlighting and code completion
When syntax highlighting was not working for me using PyDev, I discovered that there were somehow two 'Python Editor' associations defined for .py files in my installation of Eclipse/PyDev.  From the Eclipse Main Menu, go to Window  > Preferences > General > Editors > FileAssociations to see the file extension <-> editor mapping. I set a different one as default for .py files at the bottom of the dialog, and got syntax highlighting working again.
No code completion and syntax highlighting in Pydev
