There is a Yahoo Group which discusses the Cricri in great detail. It is more for the actual builders rather than the "dreamers" so if you go there as a "dreamer", please read the info (all the questions you will have have been asked before , so search) but let the builders get on with their serious discussions. Here is the site
CriCri : CriCri.
Michael Columban still sells plan sets for the aircraft. However, due to a past litigation problem, he will not sell them to anyone from the USA. As you will see at the Yahoo site, it is strongly recommended
not to proceed with the Heintz Cricket (US version) which allegedly has some design modifications which are "unsafe" and have lead to some accidents.
The Cricri is certainly a unique aircraft.
