Digital BW, The Print

Hi,
I'm new to digital B&W and am looking to buy a 13" width printer.  Since the 
1270/1280/1290 Epsons seems to be gone (except used, of course) I'm wondering if the 
R1800 is the next best thing in 13".  Is there an advantage to either the 2200 or 2400 over 
the R1800 for B&W?

Also, if I start with the R220 MIS CFS system, can I simply install these same carts in the 
R1800 when I move up?

Many thanks,
Mark
