I wouldn't buy a laptop or anything of high value off ebay because the seller generally disappear after the sale is completed so if you ever have any issue with the product you'd be stuck.. Manufacturers often do not provide support for products sold on eBay even though sellers always say the products come with such and such warranty. You would better off going to BIG retailers such as DSE, HM or the likes to buy computers as they do have good customer service. A few years ago I bought a computer from DSE, I took it home and felt it wasn't really what I was looking for, I then brought it back to the store for an exchange which I got with no question asked, I wouldn't have been able to do it had I bought it off ebay or local computer shops. Dell is also a good place to get cheap computers :)
