I want to buy something similar as well, same specs, price $300-$500. Only I'd prefer if it was from someone living in PA or NJ, because I don't want to spend too much on shipping. Also I can't buy before late August, because that's when I start college. I want to use it as my main computer for about 6-9 months until i can save enough to get a MBP.
Thanks,
Basu
