Thanks for the information.
From what I have read and experienced the brand/manufacturer makes a big difference on the performance and reliability of memory. I have also read and seen memory advertised to be one thing (i.e., class10) but when tested did not qualify for that rating. My point being that when comparing memory I think it is best to compare apples to apples and that includes brand.
I reviewed topprise for the current prices on the specific Lexar items I am offering and made sure to ask for less. However, as always, I am happy to entertain any reasonable offers.
