Over the years, I have found Lexmark to be very dependable. I've had no problems with my current all-in-one that was bought about 3 years ago. Before that, I had others that seemed to only last about a year before something happened and would cost more to fix than it did to buy a new one. Before all-in-ones were pretty affordable, I had a Lexmark printer and it still works to this day!
Personally, I would stay away from HP. Customer support is terrible, especially once it is more than a year old. Quality is kind of hit-or-miss with them.
Epson is also a good company/product, but the ink replacements are sometimes harder to find and slightly more expensive.
Currently, I have a Lexmark X5650 and it has been good to me. No problems mechanically and the 2 different ink cartridges (a black AND a 3-color) aren't too expensive. I hope this helps.
