They are on sale for $30 at Woot. Sounds a little sketchy, but I'm thinking about trying one in my DR-680.
I prefer Kingston & Sandisk for top quality, I think Transcend & Lexar are OK second quality brands, and I will avoid A-DATA from now on. Centon doesn't strike me as a top brand, but who knows? Maybe they've got the same chips as KingDisk inside? Let us know if it tests out well!
$30 for 32GB/Class 10 is CHEEEP nowadays, I'm seeing a Class 4 Kingston 32GB on Clamazon for $65.
So many bad reviews, I think I'm going to pass. I'd hate to have it fail the field test.
