Where can I buy a used Mac?

I’m thinking about getting a Mac as a second computer at home. I’m not sure I want to spend the money on a new Mac, because it might not get used much. Is there anywhere I can purchase a used Mac?
One obvious place to look for used Apple hardware is the online Apple Store. There are plenty of refurbished Macs available direct from Apple. Depending on what you’re looking for, you can find great deals there. Sometimes refurbished means the computer was a dud in the first place, so tread with caution.
Another smart alternative is to look for a reseller specializing in used Mac computers. The trick here is to find a company with a good reputation and good customer service. It’s also important to look for competitive pricing. One place you might look for a used Mac is DV Warehouse. The company has a long history of servicing the video editing industry with quality gear and they have one of the largest selections of used Mac hardware I’ve found online. If you’re wanting older Mac hardware, DV Warehouse may be the only place to find the used Mac you need.
Before you decide on a place to make a purchase, do some research to make sure other shoppers were happy. eBay is another great place to look, in part because the user rating rating system can give you an idea of what kind of shopping experience to expect. And of course, if you need an immediate solution, Craigslist can probably help you find someone in your area.
