I am still using my old HP laserjet 4 for all of my B&W work, and it performs like a champ. If you have a lot of B&W printing, you can get an HP 4 or 5 refurbished and it will outlast any monochrome laser printer made today.
On the color front, I initially purchased HP inkjets because my HP LaserJet was so excellent. But much to my chagrin, HP inkjet after HP inkjet failed miserably after about a year's usage. (And I was buying expensive inkjets, not low-end ones).
I finally moved to Canon printers, and am amazed at the quality and durability they have. I'm presently using a Pixma iP 5000 and wouldn't hesitate for a second to get another Canon if this one ever dies!
(By the way, in reliability surveys by pcmags for several years now, Canon printers have consistently come out on top.)
