Digital BW, The Print

I have two questions which I hope can be answered. since I don't see 
too many 7000's for sale is the 7500 a viable alternative when used 
with MIS inks or Piezotones.Is the 7600 an even better buy.

My second question concerns the Bowhaus software. There seemed to be 
a bit of chatter which has died down. Has anyone more information 
about this software RIP. How good is it. Will it work with the 7000 
series printers. How much is it going to cost.
