i was wondering if the u.s. and european versions are the same.
The 5736 in Europe is exactly the same set as the one in the US. (I bought them over the Atlantic, as well as here).
In Belgium the box also has 5736 as set-n°, while in Germany it got set-n° 4424. The same was done with the Pirate-treasure chest: everywhere it has set-n° 5737, except in Germany... there it is 4432. Can't think of a good reason for different numbers just for Germany...
btw: 5736 is already discontinued here ('limited release') and isn't mentioned anymore in the new (Belgian) catalogue for 2007,
but a few weeks ago it suddenly reappeared on the Belgian PM-webpage...
they probably still have left-overs in stock, and are offering it to fill in the gap between the discontinuation of the 3940 flagship late last year and the release of the new 4290 in october...
