Or should I just get a $99 USB 2.0 external BD drive from OWC/MacSales. (LaCie also sells a USB 3.0 Blu-Ray drive but it's only 6x write-speed, which means USB 3.0 doesn't really help.)

This equates to 27 MB/s and 36 MB/s respectively. Portable BR writers are either 6x or 8x, which means a max theoretical speed of n X 4.5 MB/s.
