the nord lead III seems fantastic. i had a nl 2 but had to sell it due to a great offer i got... but i still have a micro modular, though. it's great for all sorts of noises - including vocoding, which it does best out of all vocoder gear i've tested.
the nord lead III, however, will be out this summer, and it seems very exciting. see pictures and more att http://www.clavia.se
