I prefer if it would be on amazon or any other respectable site.
It must be under $100. I've never bought one before so I don't know whats good. 160GB-250GB should be good.

I found these that seems okay. Suggestions Please?
Are they good brands? And sellers?

Seagate FreeAgent Desktop 500 GB 3.5" USB 2.0 External

Western Digital Passports are sweet!

My Passport Overview

do you think this one is good?
Amazon.com: Western Digital Passport Essential Portable 250GB USB 2.0 External Hard Drive (WDME2500TN): Electronics

Yes. That price beats Newegg:

Newegg.com - 2.5", USB 2.0, Western Digital, External Hard Drives, Hard Drives

I have several of these and they are great. Pre-formated: Plug and Play.

Not to mention cool looking and they fit in your pocket.

They are SATA II 2.5" drives.

thx. i'll take your word for it and get this one. cos i wasnt too confident abt the ones i found. they had bad customer reviews but it was the best selling products when i searched. most were something abt overheating, computer not recognizing it, the plug got wore out fast ..and such

Just an update....THX for the recommendation again. I got it already. I ordered from amazon. I picked the blue one. But it didnt came in the same shade of blue displayed.
