Digital BW, The Print

I have the opportunity to buy a used 9600 printer cheap. I have a
4800 and really like the K3 inks. I used to use a 2200 and don't want
to go back to that inkset for black and white - even with Imageprint.
What are the options for 3rd party pigment inks, etc. for doing black and
white? And will I be able to get prints without gloss differential
and bronzing, either by using quad inks, or PK art papers?

ps. I'm not interested in matte surface papers. I also don't want to
get involved in clogging. So any opinions on that would be most
welcome.

Thanks,
Steve Daniel
