It's not about bashing eBay, so take a step back, please.
It's about eBay being the primary outlet for counterfeit SD cards - a LOT of Android users have been ripped off that way.
The recommendation for SanDisk is because we've yet to find counterfeit versions of those.
We're here to help Android users, not eBay - and mileage varies. AndroidForums.com is chock-full of posts from people who were burned with counterfeit SD cards from eBay and never got a dime back.
That's not bashing - those are stone-cold facts.
So - glad you found what worked for you, but around here, we like to say, let the buyer beware!
