Amazon.com: Electronics: Seagate ST3160024A-RK 160 GB External USB 2.0/FireWire Hard Drive
A few points of interest here.
1. I got this referral via Macintouch. Macintouch is a superb OS X oriented site with loyal readers. They make referral money from Amazon and they make good referrals -- like this one. Nice win-win.
2. This is an amazing deal.
3. I never thought of Amazon when I bought a firewire/usb drive recently. I should have. The user reviews are excellent and would have been most helpful.
