Check Inkjet art, their prices might be slightly less. I seem to recall that it was about $100 les, but I could be wrong.
I need to check into HP and Canon wide format service. For Epson I can't even go and pay for the training to service their printers, so you are locked into their pricing (which is often a ripoff and manty of the techs really don't know what they are doing). I'm hoping that HP and Canon have more flexible service training, if they do I might spend the money to become a certified filed repair person for them.
