As owner/technician at my own computer repair shop, I recommend Dells.
You can pick one up at Staples.
Stay away from HP/Compaq and especially Acer laptops.
This is based on my personal experiences repairing laptops for 12 years.
Note that there have been some terrible models from all companies, but in generaly Dells are slightly better. They also have the advantage of being sold in a limited number of models that change less often then other brands. The advantage is if something does go wrong, you can far more easily and cheaply pick up parts for your Dell than any other model.
