Dont any of you folks use a bulk ink system??
You just buy bottles of ink and top up each one as you need it - you can save a fortune!! Cartridges are a VERY expensive way of printing!
I have a 2100 with Lyson photocrome inks, and andother with fotonic inks...
Worth a look, anyway.

I know there are other companies that do bulk inks, but I've always found these guys pretty good, and their inks are stable, no change from batch to batch.
