Digital BW, The Print

Now that the subject of 2200 B&W has been brought up, I have a question
that's been on my mind a lot lately. I had been using my 3000 with MIS full
spectrum inks and the Piezo driver for B&W, and the 2200 for color. But
since I finally got to trying the 2200 for B&W, I was totally blown away
with the quality. Plus no banding on heavy paper, faster printing too. Can
anyone think of any reason, other than cost of inks, to continue using the
3000 for B&W? Is there any chance of selling the 3000? (If anyone is
interested in it, with remaining inks and the Piezo driver, let me know.)

Thanks,
Steve
