Think I would be slightly aware of HP. From what I hear, (This WOULD need checking) the cartridges are chipped in such a way, that older ones will not do the squirty bit as they are "too old" Lexmark are incredibly expensive to replace cartridges and from what I have seen, are a bit iffy in quality as well.
I use an Epson R800, but a full complement of 8 Epson cartridges sets one back around 80 quid. Most of the Epson range have a lot to be said for them. Canon I would live with too. Compatible cartridges are ok, but if you after good colour balance and longevity, then I would think twice - no - three times at least.
Remember that good though various printers may be, that they are simply vehicles to flog you ink. This can be pretty frightening too. Do you need a photo printer? If so, then get a good one. If you are doing occasional photo printing, then something cheaper to fill might be a good route to take. If you really need that fidelity, it is going to be more expensive. I would look at Epson and Canon, possibly HP, then work out from there.
