Digital BW, The Print

I have 2-1160's- One ( never used) has tested ok with no microbanding and has been stored in the box with a flush cart installed, and one slightly used (less than 50-8x10's 
printed) that will be flushed. I am considering selling these for I find that I do not print very much BW.  I simply get more use out of my 1280 with the Gen 4 inks. Anybody 
have an idea as to what there are worth to quad tone printers like yourself?
