Does anyone have any experience with compatible toner cartridges? The laser printer I'm currently using was bought a fair while back for £50 IIRC but the replacement cartridges cost about that. I don't feel like shelling out for a new printer just yet as I don't use it all that often but I'm starting to get patchy prints and since this printer has no low-toner warning I think it's just because the toner is running out. I've found a compatible cartridge on ebay for about £12 but I'm not convinced it will work too well because it's the sort that includes the drum i.e. more to go wrong than a simple toner container.
