Theory says if you take printing seriously it's probably safer to spend more money on a printer that'll last - e.g. one of those big ass laserjets. I have a 3 year old HP Photosmart at home, doesn't get a lot of use admittedly and has only needed two cartirdges changing in that time, but it gets looked after, moved with care and a wipe down every now and again.

On another note, having just arranged a UPS changeover for a client, I'd have loved the chance to have been able to have the old one given a FREE WEEE-compliant disposal (having said that, I'm assuming it's WEEE compliant process as I don't remember seeing the word in the article).
