The Asus GL522VW looks quite interesting. (I've got a ASUS laptop atm, a shit one, which is (surprise) quite bad build)
The MSI GS60 I suspect it this the MSI GS60 Ghost you refer to (?) doesn't seem to fall within the price range (600-1000$)
The Lenovo Y700 seems (like most Lenovo), despite their good build quality reputation, to be way out of the price range.
Mind you, that it might be my current region, which distorts the price
