Great hardware you've bought more than once

Once every now and then, you come across that great piece of hardware that, despite it breaking at some point, you immediately re-purchased right away.. Well, that's assuming I'm not the only one doing this.

So what are some of the more notable re-purchases you've made hardware wise? What recommendations do you fellow Polygons have?

For me, two items come to mind:

Razor Deathadder mouse:

and a Logitech Illuminated Keyboard:

Were any of them to break right now, I'd immediately pick up another set.

What about you guys?
