If it was me, I'd go for something like the Pioneer BDR-205 or LG WH10LS30. I'm not up on the latest external enclosures and chipsets. If it was me though, I'd look for something that supports eSATA or USB 3.0, especially if you want to read or write at speeds faster than 8x. If not, USB 2.0 should be fine.
