First of all, lets look at the options we have to get a cheap Macbook. You could start by looking at the refurb Apple Store. There are often bargains in the there of about 15 − 18 percent for new Macbooks, MacbookPros and other items in the range of computers from Apple.
Then you might have a look at the online auction sites like Ebay. Not always the safest way to buy a computer, but if you can do a, pick up in person deal and also check that the seller has documentation to prove that he or she owns the computer, you will be OK. If you buy from a reputable seller, in as much as the person has a good rating and feedback from his previous buyers, than that will be workable too.
Take a look at Craigslist or other secondhand sales sites online or local advertising. Again the same rules apply to make sure you don’t get ripped off. If you can, get a demonstration of the computer actually working, so that you have some idea of what you are buying. Make sure you have a list of what is included in the sale, regards both the hardware and software. Will it come with all the necessary disks?
There is a site where you can check all of the models of Macs that have been made and you might want to look out for things like the model numbers. This is so that you will know important facts, like can you add more memory to it. You need to know what is the maximum memory that can be fitted. If you have the model number you can go to Crucial memory and they have a memory finder that will give you that information.
The age of the cheap MacBook is vital to know also. Hard drives of any computer will fail at some point and if the computer is of a certain age the you should factor in the cost of putting in a new drive. When you look at a second hand MacBook check things like the hinges on the lid and that the track pad is working as it should be.
You should take care over buying secondhand, but it has to be said that a Mac Computer will outlast PCs and you will get many years out of a cheap Macbook. Could be worth your while to look at the Apple Refurb Store and also the new prices. Another good solution is to see what computers your Mac friends have. See if they intend to do some upgrading soon. Often they pass on their old computer to family members, but not always. You will be able to know more about the computer and what sort of care has been taken with it during its lifetime. Good hunting.
