Does External Multi-Disc DVD Burner Hardware Exists?

Dear All,

I'm wondering if anybody has stumbled across a multi-disc changer dvd burner
(external) aimed at the home user?

I've searched around, and found what appears to be commercial versions
(basing on the price) and towers which are technically duplicators.

I was wanting an easy way to burn discs whilst I'm away from the pc (remotly
connecting) at the moment I can only burn 2, as there is nobody to change
the burnt disc to a blank one...

Thanks in Advance.

Regards
Paul.
