Digital BW, The Print

This is my first effort to get into the digital B&W printing arena.

I am planning on using MIS B&W inks, and do not need to print 
anything over 8x10.

Is there a reason I should purchase an Epson 1280 instead of an Epson 
890? They seem to be the same except for the width of paper they will 
accept.

Or - is there a better option?

Thanks,
Larry
