I second TonerRefillKits. A very complete kit. The first refill takes a bit longer than others because the replacement toner is incompatible with the Brother toner so you have to spend some time making sure you empty out the remains of the original. After that, refills are quick. The Brothers are designed for easy refill (unlike the Samsung color cartridges which were both painful and prone to leaking toner). You should be able to get 3 refills out of a cartridge before the roller starts smearing. Then take them to OfficeMax or whatever. I've refilled perhaps 50 of them and it was a smooth experience. The only trouble I've had with the Brothers is that the toner level optical sensor can go bad giving you false refill indications. Covering the hole in the toner carrier with a piece of black tape can help work around that, but it doesn't solve your problem.
Also, put the date of each refill on one of the provided stickers so you can keep track of how much life your cartridge has.
