Digital BW, The Print

I imagine that this has been covered, but which is the best way 
for an experienced Mac based digital photographer to get 
serious about digital printmaking? I've been involed with imaging 
for years, even had my own IRIS for commercial work, but tried to 
ignore the whole concept of archival inkjets. But now I see that 
they are 'ready for prime time" at a reasonable price. I'm leaning 
towards an Epson 1160 with Cone's Piezography™BW software 
and inkset, but I see an awful lot of people using MIS inks. Has 
anyone out there used both and can give an honest evaluation?
Is the 1160 a decent machine given its size limitations? 
Thanks,
Frank
