You pretty much can't buy Lenovo in Brazil (I mean the Thinkpads).
Dell is established, affordable, good customer service. Competes here with Acer, HP, Toshiba and even cheaper brands probably assembled in Brazil (like Positivo).
Sony Vaios are normally a little bit higher priced, closer to Apple.
The lower end Dells start around R$ 1700 (820 USD): Core i5, 4GB Ram and 1 TB HD. The higher end (gaming or slim) ones, my guess would probably be around R$ 3500 (1700 USD).
