Desktop Computer

Help me! I am writing here from my friends computer because I feel some traffic at this site, I see users are reading here. My computer broke! My DESKTOP COMPUTER broke. I was looking at many auctions and I am so confused what to select. I don't know much about NOTEBOOK BRANDS, I feel so dumb and don't know where to BUY REFURBISHED LAPTOP. 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 kindly help me and tell me what to buy? I just did not see other stores then fashionlaptops.com site with a big choice. Please help to select something good and cheap. Thank you!
