Looking to buy an external hard drive

yo, tried searching but it didn’t find anything.

I have a fairly small HD on my PC(160 gb) but i’m content with it. I need to buy an external HD to back up my files so I can reformat my pc. I’m looking on new egg and see a bunch, but I don’t know what brands are good and what I should stay away from???.

I would like to spend no more than $80-100.

here’s the link to new egg
