I won't be buying one. I've never bought one of the paper shredders either.
I have a bucket which I line with a plastic bag. I take this bucket and a little garden spade around the back yard to patrol after the dogs. When I have some papers to dispose of that are of the nature of which most would shred, I just crumple them up and put them in the bucket. When somewhat full, I take the plastic bag out, tie a knot in the end of the bag and put it in the garbage for transit to a landfill.
Who figgers that if anyone wants his papers bad enough to go into that plastic bag, they are welcome to them!
