Digital BW, The Print

Hello all!  I'm looking to get into doing some quality B&W 
quadtone printing and am looking into purchasing the 
Piezography software.  I'm on a tight budget though and was 
wondering if anyone wants to sell their license for this software.  
Maybe one of you out there is using another workflow and 
doesn't use the Piezography driver or something like that.  I have 
an Epson 1160 on the way that I bought used for $100. and am 
looking into getting a CIS from NoMoreCarts.  Are there any other 
options that I might want to look into for software?  Thanks for 
reading.
