Any Enclosures that will work with my Macbook?

I just updated my 80GB macbook HD to a 120. Now I have a 2.5" SATA HD that isn't doing anything so I figured I best get an enclosure to utilize my extra 80GB. What have people been buying for these? My problem is 2.5" SATA enclosures are somewhat expensive. Does anyone know of a cheap one? I prefer USB 2.0, firewire is acceptable if the price is right. If their is one that would look really good with my white macbook I would consider it even if it is kinda expensive.

Also, another thing I've been looking at is the Bluetooth Mighty Mouse. Does anyone know of an online retailers that are shipping them imediately. Apple seem to be having troubles filling orders for these and the ship times are close to a month from order time.
