Digital BW, The Print

Hello,
Great that a thread started about how to enter the realm of digital
printing. I follow this list's discussions but quite a lot is above my
head at the moment. One thing I did understand: you have to start
somewhere. 
Since I am in the market for a new office printer I try to get one that
will allow me to start printing also photo's. I have quite some
experience in the B/W wet dark room, have a simple 35 mm scanner.
(photography is not my source of income at the moment,that's , a. o.,
documentary and informational films)
Epson launched the C70 and C80 some time ago. I remember discussions on
this list on the C80 but was unable to retrieve it. The C70 is nearly
identical, a bit slower, but the same ink set. The C70 is on sale now,
here in the Netherlands. 
Yes, I know, it's not a dedicated photo printer (neither is the C80) but
I remember some people on the list were quite happy with the C80. If I
start with this unit, I can go on later with a dedicated photo printer,
leaving the office work to the C70/80.
What I want to know primarily is:
Are third party inks / CIS systems available for the C80? 
Do these work also on the C70?
Any other comments or links?
Thanks very much in advance!
Best,
Ton Guiking
