This is one of those things where whatever price is right for me, Kingston, Sandisk or Lexar will be my choice. As long as they are the same speed and or the right size i'm looking to purchase.
I did or was geared to Sandisk because of an article or experience I read/heard where someone forgot to take out the CF card out of their pants before laundry and when the laundry cycle was done, the CF card worked flawlessly. From there the rumors flew around stating that it has weathersealing and what not blah blah blah.
how truthful it is, well, I never had any issues with any of the brand cards. Although I only will stick with LExar, Sandisk and Kingston, nothing else. I think much of it is what makes you feel comfortable.
not to go to a tangent but I will never touch a western digital external drive. Why? Because it has failed on me twice, almost losing all my data (thanks to a recovery software I used). The bottom line is, there will be people out there that swear by Western Digital.
