WHAT C++ ? (RS-6000)

[Dimitrios Rizos]

  Hi there

  Would someone please inform me on selecting a   C++ compiler
  for the RS-6000 ?

  My specific questions are:
          1.  What compilers exist ?
          2.  Info about any one of them and in particular :
                              How much would they cost me  ?
                              Their strengths and weeknesses,
                              Where could I get them  ?
          3.  Where can I find info about them ?

  Any comments are very much appreciated.  Also rating the
  different compilers by price and/or performance would be
  extremely helpfull to me !

  Thank you everybody in advance.
