I took my 'buslink' back when I discovered that there are two 'types' out there. I went to Staples in Hackettstown, NJ (where I recently purchased the drive for $50 after rebates), and they only had the 'justlink'. They called the store in Chester, NJ, and indeed, they had the 'smartburn'. It was some run-around, but worth it as it cleared up a buffer under run error I was having with the first drive.
Nothing like a Lite-on!
PS, if you have already purchased the Buslink 52X24X52, the LITE-ON is clearly displayed in the device manager. The last one appeared as " 52X24X52" - yes, the space is on purpose. The front of this drive is also labeled with 52X24X52, while the "Justlink" version had no writing on the drive face.
Here is the link to the model it came with: LTR-52246S
