I've owned two HP color LaserJets, the first was a CP2605DN and now I have a CP2025DN. Neither required periodic drum replacement. Nether like third-party toner cartridges, either. HP toner is expensive and even though I only have to do it about once a year, it still hurts to shell out more than $400USD for a set of toners.
That said, I'm not going back to inkjets. I'm actually saving a bunch of money with the color laser printer compared to what I was spending on ink cartridges.
