Digital BW, The Print

Hi,
I printed some very very nice looking BO-prints
with my claria r280 (r285 here in Germany) printer an the claria black ink. With the qtr-profiles from 
Carl Schofield (thanks for these) I did some prints on Harman
Fiber Base Gloss and Epson Premium Gloss, which really look 
good and (esp the harman) make me think seriously about giving up my darkroom
if I could have this bigger than letter-size. 
Now I want to go on in b&w black only printing and
I´m thinking about buying (ebay) an r1800 (and the mis inks for mk-3 on matte papers) or an r1400
(claria- BO on Harman fiber base gl.) If I put longetivety and the glossy-matte question
 aside.
What difference concerning smoothness, image-tone, and "look" can I aspect from
the two different aproaches. I hope there are some people out there wo have seen 
prints from both systems.

Marcus
