Digital BW, The Print

I'm making the jump to a wide format printer for Piezography very 
soon. I received an email from a place that has Epson 7500s for 
$1995. My question is: Is the 7500 as good as the 7600 for B/W, or 
should I spend the extra $1k and go for the 7600? I also plan on 
buying a 7600 for color, so if I can save a few dollars it would be a 
bonus. Thanks in advance.
