QTR-Quadtone RIP

Hello all and thanks for the privilege of posting. I just 'inherited"
two 7000s and wondered what the current thinking is regarding this
printer as a dedicated B&W machine. I have reviewed the archives and
it seems that some people are getting great results with this machine,
though I have to say I've been less than enthusiastic about it's
suitability for color. Any suggestions as to the best available B&W
inksets? Any problems to anticipate with QTR on a G4 533 running 10.3.9?

Thanks all... I appreciate your patience with a "newbie..."
