Yamaha FS1R.
Probably the most advanced FM and Formant synth I ever dealt with. It's strong point is it's formant capabilities, wich allow to produce sounds and loops that just blow your mind. Nothing close to it out there.

Novation nova table top.
Portability, ease of use and great sound.
it does just about everything that all of my favorite analog synths are capable of.
It may not be as complex as NM but its pretty flexible and it sounds ****ing great!
