Digital BW, The Print

Hello. I just joined the forum. While I have known about Paul Roark's work with B&W for a few years now, I have just begun the learning curve for B&W processing and output. Which means I need a new, dedicated B&W printer. My income is only disability so I must keep expenses as low as possible. I have an Epson 1400 that I will continue to use for color work, but do not know the best option between these two smaller printers. The least expensive seems a little more difficult to convert to B&W. I have been researching all morning and have ended up confused.

What I would like to know is the easiest (one set of pre-filled carts hopefully that could then be refilled)as well as the least expensive solution over time -- that produces the optimum for a 4 ink printer. I see mention that Paul uses a combo of EZ neutral and warm inks in some cases. For tone, I would choose Neutral overall (unless the two warm tones that Paul uses still produce a basically neutral tone). I would like to standardize, in the beginning, on the PremierArt matte paper. 

Your input will be much appreciated.
