Oh the way I mean it is that although I do agree that it is incredible to get an 8300 for just a few hundred more than a 6300, which of course gets you way more ink, its not all usable ink. More ink is being used in the priming of the lines, and each cart is just so much more expensive when you have to replace it. The big hit is when you start having to buy more ink carts at $170 a pop. You might just replace 5 or 6, and then the printer dies, and then you have to figure if its more cost effective to buy a new printer, or perhaps new print heads. It happened to my 6100. Had to buy a $500 print head, and hoped the other one didn't go. And since then, only a few months ago, I've probably bought 8 or 9 carts. So if the other head goes very soon, then I've just pumped lots of money into a printer that I can never get back if I don't get to use up what's already in there.
So all I mean to say is that although it is an amazing deal to get $1700 worth of ink or whatever the number works out to, you will never be in a position to use up all the ink at once and retire the printer. That extra ink might only work out to $700 extra cause $1000 will be left in lots of ink carts that may be more than half full when the thing dies.
