Sager and Prostar are actually "sister" companies owned by the same families in Taiwan. All of their notebooks are designed by an ODM (Original Design Manufacturer) called Clevo (
www.clevo.com.tw). Also, the Alienware Area 51-M is the same notebook as the ProStar 5694! Alienware just colors the case and adds about $500 to it
ProStar has been in business about 11 years while Sager has been in business about 15 years. You can't go wrong with either one. Just make sure the reseller will back it up too!
