A PS3 Controller
Gamers know that the cost of their hobby isn't cheap. Whether you are buying systems for upwards of $200 or games that cost $60, cutting corners is essential if you are gaming on a budget. If you find yourself in need of a new PS3 controller, expect to pay $55 for it at a regular retail store. However, if you don't mind shopping around or purchasing something used, then you can purchase a PS3 controller for much less.
Buy Used
Gaming giant GameStop is a very large purveyor of used goods, and while they are most famous for selling used games, they also sell used controllers as well. Purchasing a used controller will generally cost about 20-30% less than new, and if you purchase one from GameStop, the controller is guaranteed to work, so you don't have to worry about purchasing another one if the controller is broken.
Look to the Internet
Many times Internet retailers like Amazon.com can offer substantial discounts on PlayStation 3 controllers, and can offer free shipping in addition to their deep discounts. You can also check sites like eBay and Craigslist, which have individuals selling their own controllers for very low prices. However, beware of sellers who would sell you a broken product, and make sure to research sellers or, if buying locally, ask to try the controller before you purchase it.
Non-Official Controllers
If you don't mind using a non-Sony PlayStation controller, there are plenty of options. Peripheral makers like MadCatz, Logitech, and DreamGear all have their own versions of the PS3 controller. Although the controllers will look a little different, they will interact just fine with your console and generally cost 30-40% less than new Sony-branded PS3 controllers.
