I used Labels By The Sheet for a while, but had spotty quality. I requested a sample from WorldLabel.com and they were the best I've used so far! They don't come in small quantities, but their customer service team sent me a few sheets to test for free! I buy the laser print ones and take them to FedEx - unfortunately there's always some sort of issue with margins or not printing in alignment with the cut label, so I too am looking for a better solution, but it works for now!
