Asus BW-12B1ST 12x SATA Blu-ray Burner for $51.99 shipped after using code EMCXMXW43 and this $20 rebate. Here is a screenshot before the $20 rebate for your reference. It writes Blu-ray at 12x and DVD at 16x. Note that it comes in OEM packaging, which means no pretty retail box but the drive itself is otherwise identical. Most places have it for about $73.
