Anyone who buys a color laser printer should be aware that the initial cartridges, at least from HP, are not as full as refills, so you will have to replace them fairly soon and it is expensive. That being said, the refills will last a looooong time.
Also, and the main reason why I purchased one, the printer will just work, even if you don't print anything for a couple of weeks, or months even. I went through a couple of inkjets (not the cheapest ones), which would constantly get dried out, a head clogged, etc, before I said "fuck it," and sprung for a laser. My wallet isn't that happy, but it sure is nice not gambling on whether the damn printer will actually print.
