Shoot me first. LOL
Unless you are looking for a 7700 to just mess around with and don't care if it blows up, stay away from that line all together.
I would look into getting a new laptop with a warranty. If you can't get an Alienware, check out the Dell XPS series. Pretty good bang for the buck, IMO.
As others have stated, I've heard good things about Sager, although I have no first-hand experience with them.
I dont know of any XPS 17" lappys that are around $1500 new
