Desktop Computer

Please help! I am writing here from my friends computer because I smell some traffic at this site, I see users are reading this page. My computer broke! My NETBOOK broke. I was looking at many online stores and I am so confused what to select. I don't know much about LAPTOP BRANDS, I feel so dumb and don't know where to BUY REFURBISHED DESKTOP PC. I found lemanskef.blogspot.com (you can see it here, - but they have so many of them so I am really confused what to buy. Can you please help me and tell me what to buy? I just did not find other stores then fashionlaptops.com site with a big choice. Please help to select something good and cheap. I appreciate your help!
