dont worry, you're not the only one who cant afford something like that. For a good 7200rpm hdd i would personally go with this one : http://www.newegg.ca/Product/Product.aspx?Item=N82E16822136792
You cant go wrong with WD (except for their green serie).
Thank you very much. Actually, I was also making a decision against the model you suggested and was doing a market suvery. Unfortunately, this part of the world where I live, don't give us much choices. If I can't find it in the local market, then I will get it through amazone (the only next option)
Regards and thanks
