had one and are still in good contact with several owners. Nice bike, komplete 600 AX except the Dura Ace AX front derailler. Frame is lugged Aluminium, the Kettlers are not extremely lightweigt but okay. Tubular rims, very nice aerodynamic Nitto bar.
Pictures of mine are here: http://www.radbasteln.de/
When buying one, keep care that the bottle and the holder are in good condition as the bottleholder is part of the shifting system (see pictures). This bikes are still not rare in Germany. Was a highend one at its time but german highend bikes were not as nice as french or british or italian ones were. Form clearly followed function... no blinkblink, no funny colours, a Kettler is a serious bike ... :)
