Elektron Musical Instruments

What other unique HARDWARE is out there the Elektron Users would recommend?
By unique, I am not talking about analog-style (Access, Waldorf and
Clavia are all excellent). I am talking about different.

Any ideas?

As far as 'uniqueness', the Hartmann Neuron is about as unique an approach
to synthesis you'll find now - though cost a bit more than an evolver :-)
