I have a monochrome laser printer which is several years old and prints just fine. However while printing it gives me a message that the printer drum needs to be replaced. It's a Brother printer, a new printer from Brother costs about $125. If I get the drum from Brother the drum will cost $94 plus shipping, so that clearly makes no sense. I can buy a drum for about $20-25, there are several sellers on Amazon at this price, however the reviews range from one star (it's junk) to 5 stars (it's great). Anyone have any experience with these after market printer drums?
