Digital BW, The Print

Hi all, let me start out by saying I am very knew to the whole digital printing realm so bear 
with me if I am a bit slow.  

Basically what I want to do is print B&W only, and really would like to use Museo Silver Rag.  I 
really don't want to bother with large size printers because I have neither the room, nor the 
desire to print any larger than 8.5x11 right now.  So ideally I would like to use the R800 or 
would use something cheaper too if it meant it was easier.  

So any suggests as to what the easiest way to do this would be?  I'd like to use one of the specialty ink sets, and have been leaning towards the MIS but will use anything that will get 
the job done.  What the dilemma for me so far is I know I need a PK ink for the Silver Rag, 
but most of the black ink solutions seem to be MK as far as I can tell.  So any links to what 
would work on the R800 or similar smaller printer would be greatly appreciated.
