If you're looking for external Blu-ray burner, some of the available choices are from Lacie, Buffalo, Samsung and LG. But in the US only Lacie D2 is available and some custom made external drive (internal drive + third party external case.)

The Lacie d2: http://www.lacie.com/us/products/product.htm?pid=11054

Or you can wait for LG BE06 which will be available very soon: http://club.cdfreaks.com/f142/lg-gbw...drives-246246/
