We just bought a shredder not too long ago. We only paid $35 - $40 dollars for it because we don't use it for more than shredding bills and personal papers at home. It's an Aurora and we bought it at Staples. So far it's working just fine.
Did you know that you are supposed to oil a paper shredder? Directions are included on how to do it. We didn't know that

and I think that's why we ruined the motor in our last machine.
Are you looking for a simple shredder or one that is more substantial and can take on bigger jobs?
