This may sound a little odd but one of the reasons to buy a Canon Pro-1000 is if it were to break down and need replacement, it makes financial sense to do so. They run between $1000 - $1100. It comes with $720 of ink. If you transfer your old ink cartridges (some will run out filling the lines and heads, in that case use the new ones) so you gain a lot of ink for having to replace the printer, offsetting the cost.
