Solid State Drive

I currently have a Corsair SSD that has (and still does) serve me faithfully since I first bought it 2 1/2 years ago. However, times change and so does the wearer of the Solid State Drive crown. I'm interested in purchasing a 64 GB SSD meant for testing purposes in various older computers (SATA II, if that). From my trending research, Corsair, Samsung, Intel, and Kingston all have good solid state drives. I'm wary of using the Western Digital or Seagate drives, however.

So, I ask you, the Verge populace, which is the best 64 GB solid state drive that you would suggest for my purposes?
