Faller has manufactured quite a few models of German rides, especially spectaculars. They are definitely not for the novice modeler. The tooling used to make the kits is excellent, and the design engineering is first rate, considering the limitaions of the size. The only problem is that production is limited. Once they are sold out it may be years before they are produced again. I have seen old Faller rides go for ten times their original price on eBay. They have a website, but it tends to show only the newest releases.You used to be able check a great many of them out on the Wm. K. Walthers website, but the last time I looked they had absolutely no stock. There is several amusement model builders sites on the web, I just don't have them in front of me right at the moment.
