[NTG-context] GFS Fonts, especially GFS Bodoni, Didot and Porson

Hi, a few days ago Alan Bowen wrote about his problem using GFS Bodoni. I'm looking for GFS fonts. The link http://www.greekfontsociety.org/pages/en_typefaces.html seems to be dead. So can anybody provide me with these fonts or send me a working link? It would help a lot if he could add all the needed afm, vf, map etc. files to use them with context. Thanks in advance Chris
