I searched the WWW for MSWord->PDF converters (see REQUIREMENTS below)
and found several programs which did not match my quality requirements
(see QUALITY).
Instead of continuing the search and test many programs myself, I turn
to you to help me.

REQUIREMENTS:
   * MSWord => PDF converter
   * runs on Linux (not Windows)
   * command line program (no GUI)
   * free software (e.g. GPL/BSD license)
   * quality: simple documents with included images and some visual
effects are rendered correctly and look similar to the original.

QUALITY:

The last point is important: I found many programs that are excellent
for *reading* the contents of a MSWord document (where the precise
redering of visual effects can be ignored).  I need a program that
usually renders the page similar to MSWord.  It's ok if some features
(such as Word macros) are not supported.

I am looking for a list of programs *ranked by quality*: More precise
rendering at the top.  I am not interested in a long list of programs
that I have to test all by myself.

BONUS: If the first or second program in your list renders
satisfactorily on three sample files, I will pay a bonus of 20$.
