I would be careful going with cheap laptop brands. I have seen very little reviews (reviews that are competent) about them. A laptop is a big investment wheather you go cheap or expensive. My advice is shell out or save up more cash and get a solid brand and model with good reviews. It will be worth it in the end. Plus the upgraded warrenty is a must. Stuff happens, upgraded warrenty = good! parts for these are expensive. I would reccomend going to hp or dell websites and building a custom one. You dont have to buy it, just build it online and get a good taste of what you really want/need/can afford.
Sony = paying more for the "sony" on the front
Dell = Average and popular
