Probably the best B3 clone is currently the MAG P series..

http://www.magorgans.com/?box=the-p-series

Its custom build to perfection in Germany and based on the HX3 module, and at a price comparable to the Crumar..


Also the Nord C2D and the UHL X3-2(based on the same HX3 module)


And dont forget about the midi based version of the Crumar, the GSI XM122..


They are all european builds, the B3 cloning scene is quite large in europe...
