Advice for portable hard drive please

[Excalibur55]

I'm in the search for a portable hard drive to clear out some non-essential stuff inside the hard drives of our 3 systems in the house.

I don't need anything fancy; it will be a secondary storage for web pages, podcasts, images and Office documents.

I know zilch with that kind of products since the old Zip 100mb floppys; ideally a model with 320GB or 500GB of storage space is plenty enough for my needs. My budget is around 80$ or lower.

I just need a reliable and quiet product. I'm in Canada but will be in New York city the next weekend. If you know any good brand and store there; please let me know.
