What's the state of a  CIS for the 1400?  For years I had one on my old 1160s, and they were great, virtually trouble-free.  When I got my first 1400 I put an Inkjet Mall CIS on it, and had nothing but trouble. I guess the chips change everything. I would have kept my 1160s, but there weren't drivers for them as the Mac Oses advanced.  I thought it was the 1400 itself that was problematic, but it turned out to be the CIS.  It appears now that IJM has given up on CIS for that printer.  My problem today with the printer is that I get so few pages from cart refills.  Seems like I refill, print a few text pages- not even images- and that's it.  Carts empty.  I long for the days when I could just top off bottles and print as much as I wanted.  Is that still possible?  Is there anyone making a reliable CIS for the 1400?  I see where MIS has one- has anyone had good luck with it?

thanks,
