Here is what I do not find attractive about HP's:
1. Constant introduction of new cartridges. Since the printhead is integrated into the cartridge, that means you will have a hard time finding anything remanufactured if you want to save a few bucks.
2. It would not be so bad if HP gave a better bargain with their new cartridges, but every time they do this, the cartridges become smaller. Their old #45 Black use to hold 42ml of ink and cost $30. That is when HP's were more economical. The newest $100 models now use the #96 Black and also cost $30. Too bad they only give 21ml of ink.
3. If the ink cost were not bad enough, HP bundles 1/2 size cartridges with their printers. So be prepared to add another $65 to your initial purchase price within a month or two.
4. The only way to print economically is to refill. Unfortunately, there are a few gotchas. One being the cartridges are opaque which leads to guesswork when refilling. HP also uses a single tri-color cartridge, so one could easily contaminate the inks by mistake. Even after you refill, you must get your system to recognize the refill. For this, you must do the 3-cartridge or cover-the-pin swap. If I had a delicate touch and did not mind refilling every month or so, I would have kept my HP. Instead, I just sold it.
