The DU Lounge

With 30 LaserJets, 2 Inkjets, and a $3,000 wide format Inkjet, we decided the lesser quality, leakage and other problems, and the risk for machine damage was not worth the savings from "compatible" cartridges. For home use, I've had positive results from a place called Inktechnologies.com - their customer service people are friendly, knowledgeable, and speak clear, intelligible, unaccented English (and generally, free shipping.) Then again, your mileage may vary. And, of course, in many cases one can buy a new printer for less than the cost of a set of OEM cartridges.
P.S. We also tried refilling our own ink - a huge, messy mistake.
