Good 3.5" HDD enclosure?

[jji7skyline]

I have one of these.

80GB version.

And I would appreciate it if you could recommend a good enclosure for it. I'm pretty sure it uses the IDE connector.

I have an iMac so USB or FW800 connector is fine.

I live in Australia, so if you recommend an online store, please choose from ones based in Australia, or those with worldwide free shipping.

Oh, and my budget is Australian Dollar $20.

Thanks guys
