Digital BW, The Print

I was thinking of adding a printer to my toolbox in the next few 
months.  Maybe a 1280 and was trying to decide between MIS VM inks or 
the indelible/perpetual set (B/W vs archival color)...

In the long run I'll have the C80 for small proofing & office stuff.
Have the 3000 for larger things (Lysonic E color in it now).  
The 'new' printer would be for mid-size work.  There is the potential 
of replacing the 3000 with an imaginary printer that I think would be 
a large version of the C80, that would probably become the dedicated 
printer to B/W, if it were a 4 color.

Perspectives?
Thanks
