Agreed with the product selection of @michellebanjoman - go to that link which she share, there you will find that store where from you can buy this and other paper shredders in very fair price.
Strip cut shredders are everywhere, and cheap. And worthless. Anyone with serious intent and some patience can easily reconstruct strip cut documents. You need one that does fine cross-cut (confetti) or fuggedaboudit.
