Need some help choosing a laptop.

I am going to be getting a laptop or netbook by the end of this year, but it has to be $600 or less. Normally, I’d use newegg for this, but I am thinking about purchasing from a manufacturer. Has anyone had any experiences with purchasing from a manufacturer; which have the best support and customer service? I am leaning toward either Lenovo or Toshiba, but I am open to suggestions. The laptop I get has to be as powerful, durable, and able to run Blender. I may put mint or some other version of linux on it.
