Looking for a good 2.5" HD Firewire 800 Enclosure

[markwco]

I am looking for a enclosure for a 2.5" SATA preferably Hard Drive. In the past I've always used the Lacie Rugged Hard Drives but to save money I decided this time to buy my own hard drive and case and then I will upgrade it and hopefully save money in the future going this route. I am interested in getting the 500GB Hitachi Travelstar 5K500 which is SATA. I'm using this with a Mac Pro but for being futureproof I want USB 2.0, Firewire 400, and Firewire 800. I'll be doing backups to it using SuperDuper. I want the small size since it's store in a safe and space is limited so desktop size hard drives are out. Any suggestions of a good rugged enclosure that will work well on the Mac?
