R1800 Question

Hi all,
Has anybody that has a R1800 Epson Printer ever worked out how much it costs to produce a A4 Print taking in Ink & paper costs. I buy a pack of Pearl Ilford at $99 so I know thats about $1 per sheet
How many A4 can one expect to get to a full set of ink tanks, it's just that I seem to run out of these little buggers fairly often and I don't print that much.
Why didn't they make bigger tanks or keep the smaller ones but at a better price, I purchased some from Harvey Norman at $16 a tank. Is this good or can I get better.
Thanks,
Mic.
