Canon 900o refill: Precision Color or OCP?

Ive used both with great results but finally decided on OCP inks as they are, like you mentioned, far less expensive.

I would highly recommend a color calibrated and profiler such as the colormunki photo. I purchased one shortly after my printer and it has paid for itself over and over again with less waste on paper and ink due to reprints. i would pay twice what i paid for mine if i had to!
