Hoi die Willem !
Could you post the links where the cultivation is described as easy?
With the seller pflanzensucht at ebay you can be pretty sure to get what he offers - he is member of our Forum as well, but under his usual nickname RealTreder.
Chris is one of the people in Germany who collects Amorphophallus for a very long time already and he knows worldwide many people who are the usual suspects in regard to collecting Amorphophallus.
You will also find him in the facebook group moderated, when I remember it correctly, by Marco Motta.
He uses the pictiures from the IAS, because he has the OK for this by Wilbert Hetterscheid and others who provided the pictures.
But he has also a lot of own pictures:

So..... Happy bidding, Bernhard.
