Bill,
The shredder I have in the office shreds up to five pages at a time and is made by
Secure Shred . It has an auto on/off mode that prevents overheating and the only time it ever jammed is when staples were missed and jammed between the blades. My wife purchased it for about $30 from some mail order outfit about 5 years ago.
Of course, there is another option. If you have a wood stove in your home, those papers will be just fine in place of kindling to fire up those oak logs. Prior to purchasing a gas-log stove the wood-stove was my shredder.
