[DeTomaso] NPC Any Recommendations for Remanufactured Laser Printer Cartridges

[Ken Green]

Tired of paying over $100 for new Canon 120 cartridges and picked up a backup printer for $200 so I'm not as worried about a remanufactured cartridge damaging the printer.
 
Does anyone know of a specific US source for remanufactured laser printer cartridges?
 
Has anyone tried just adding new toner to a once used cartridge?
