Digital BW, The Print

Hi all, 

I wish you all a happy new photographic year! 
I'm still running with my (old) SP 1400 equiped with Eboni 1.0 (I have
some stock), but it's time to think about the next step. Unfortunately I
will have to change the ink in a short term, and the printer in a medium
term, having in mind that the 1400 is not very robust. Changing to new
inks on my 1400 will probably not make any sense...In order to save time
and secure my digital lab, I'm thinking about buying a new printer and
equip it with new inks in order to configure this new system while my
current one is still running. 
So the questions are... 
1. Which new printer (A3+ or, why not, A2+)? 
2. Which new carbon ink? 

I know that my questions are quite wide open but I really need to make a
brain storming before making up my mind...
