I think you'll find it a good move.
PLUSSES
Great variety of sounds
Matrix-type modulation routing
Extra envelope;2 LFOs;2 note-on function gens. and one Free-run FG
Ultra stable digital filtering with almost 200 available models
Total control of sample looping
Program cards are standard PCMCIA SRAM (can be had cheap)

MINUSES
Front panel editing a bit tedious
Chorusing uses up polyphony fast
Some filter models do unpredictable things to the output
No company support unless you need a manual
Planned expansion was cancelled
