Hey all, Just thought I would let you know. I was looking for an optibay or OWC alternative that was a little cheaper. The OWC version looks really nice, but i see no need for a pretty thing that no one will ever see. Searching amazon, I found this. http://www.amazon.com/Drive-Unibody...H2US/ref=sr_1_1?ie=UTF8&qid=1328715224&sr=8-1 This is made for the unibody MBP, (i have 2010 Model) It works PERFECT, and is only $18.54 Shipped! No vibration, and it even has screws on the bottom that actually hold the drive in place. Best bang for the buck!
