Buying any computer can be a tricky affair with a dizzying array of hardware configurations. Buying a used computer however is practically a minefield. Sure, you might go into store and get lucky, and end up finding a quality computer at a discount rate. It is however just as likely that you will end up putting your wallet down on a mine in said field. Then you will have spent a lot of money for something that you are going to have to replace much sooner than you would like.
That having been said there are some things that you can do to help avoid spending your hard-earned money on a machine that will give you less than stellar performance. With a little bit of care and diligence you can be sure that you’ll get a machine that meets your needs.
That brings me to my first point. What exactly are your needs? Before you just give me the short stock answer,”I need a new computer,” hear me out. I am asking you what you need the computer to be able to do, how you are going to use the computer. Obviously, if you are remote database and systems administrator you are going to have different needs than an avid PC gamer or a student attending an online university. You will never get what you want if you don’t know what you need. Go ahead, and take some time to think about this one before you go shopping. It is much better to take a little bit of extra time and get things right than it is to waste your money.
Now that you know what you need from a computer we are going to talk about pricing. This is after all, why you are getting a used computer and is not a new one. That means, despite what you might think, the first thing you’re going to do is look online to see what a new computer would cost you. After all, you don't want to end up paying new computer prices for old computer equipment. Now that you know what the noted new computer should cost, know that an old one should be at least 20% less. Based on that fact, and your budget, set a price range that you are willing to work from.
Now you know that it is time to find yourself a reputable online retailer, or make your way to a brick-and-mortar computer reseller if you have a local one. Examine the models in your price range to see if they meet your needs. If they do, then get yourself the best machine for the price. If they do not then you should move on to a new retailer. It is always a good idea to comparison shop when you are getting used hardware. After all, there are plenty of people who would be willing to overcharge you for the privilege of buying their hardware.
Now that you have your model you can go ahead and make the purchase, unless you have a very good reason to think that there is going to be some kind of a sale or bargains soon, and you can afford to wait.
