text: who is a reputable seller of used laptop, notebook, computers?   dell, gateway, and other new computer vendors also are good sources for direct purchases of used laptops.  for third party sources, i've always been happy with ubid.com, and if you study the ratings carefully, ebay can be a good source as well - my general rule is to buy from sellers who have at least a 97% satisfactory rating, and who have at least 500 transactions.
