I'll give you this advice. Spend the most your budget allows, and try to consider the following features, the the most important things first:
*Ability to shred credit card, optical discs, staples and large paper clips.
(This usually comes with the ability to handle more pages at once and is less prone to jam - jamming sucks))
*Cut type:
At a high level, there are three types of shredders:
Strip-Cut: Cuts the paper into strips. Pretty much useless. ...
Cross-Cut: Chops up the paper into little bits. This is the type of shredder a lot of people use at home..
Micro-Cut: Turns the paper into confetti. You're not putting that document back together.
*If you shred a lot, get one the can go for a while before shutting off to cool down.
*If you shred a lot, try to get one with a bin larger then 6 gallons or you will have to stop and empty it often.
*If you move it around, get one on wheels.
