leather/aluminium ipod cases

[kokoshka]

I know that I've seen aluminium cases for the 30gb ipod somewhere, but I can't remember where. Does anyone know where to look, or better yet, does anyone have one, and if so, is it any good? I'd settle for a leather case, but there are so many. Again, if anyone has one, which one, and how is it?

I've got the Belkin kickstand leather case for my 60Gb 5g. No complaints here, just wish I'd bought it sooner, then my iPod might not be so scratched.

I've got a Piel Frama leather case - excellent quality. Got mine on eBay for about £30.
I think that Proporta make aluminium cases for iPods. I got one for my PDA. Again excellent quality, and should resist any knocks. I think that a leather case would offer better protection against dropping, though.
