Digital BW, The Print

I'm quite new to this group and I am getting ready to order a new Epson Printer, I'm torn between the R1900 and the 2880. I print both Black and White and Color, probably more so color.  Is there really any advantage to the 2880 over the 1900 taking into consideration the price difference. I consider myself an advanced amature photographer more into portraits than anything else.  I've been following the discussions here, and want to start developing my black and white skills.  Any advise would be appreaciated.

Thank you

John
