Bob,
I would try to work them down a bit on the demo machine if thats the one your wanting. $2,500 off gets them down to about their cost on the machine. If they are not willing to budge it is a good deal at that price as long as it has a full warrenty.
As for the bulk ink system, there is only 1 good one out there that I have found and it is the Triangle system distributed by nu-sign. You can check it out at the below link.

The bulk ink system for the Versacamm runs at $1595.00 which comes with a new pump, dampers & wipers as well as 4 liters of ink. This is the only system that Im aware of that will actually warrenty your machine if something goes wrong. Also this is the only system I know of with any significant amount of profiles.
If you have any questions about the ink system please feel free to call me at 832-515-6458. Ive been running these inks for about 4-5 months now and one of my buddies has been running them for about 6-7 months. GraphiXtreme has also been running it for a few months as well.
