Drool over this beautiful, blue PPG 2.3 and Waveterm (that's the rackmount CPU unit with the big screen), which would be perfect for recreating the first Pet Shop Boys album or as a centerpiece for any stylish apartment. Two days to go and no bids yet at £1,650. Alternatively, there are tonnes of free PPG samples here at Hollow Sun.
The PPG was invented by Wolfgang Palm, who went on to found Waldorf and create the utterly awesome looking Wave, which looks suspiciously like the Moog Voyager. Make sure you don't miss this picture of Jean Michelle Jarre on that Wave page...
