USB DVD-RW drive

[Andrew Konosky]

I have been wanting to get a DVD-RW drive and recently someone suggested 
I get an external drive, which I had never thought of. It will be more 
expensive than an internal drive, but I could use it on all of my 
computers to backup data, with less hassle than an internal drive. Also, 
I might be getting a laptop later on, so I would be able to use it on 
the laptop as well.

Are USB DVD burners well supported in linux? If so, which models would 
you recommend? I would prefer a dual-layer capable burner if I can find 
one in my budget.
