I buy the cables from china, not the card. My LSI 3008 is from a professional german shop, i paid 150€ for it, and is absolutely genuine.Real pro-tip--don't buy fakes from china and get a genuine used card and cables for truly trouble-free operation.
The chinese cables are great, and the correct price level. Western made cables are daylight robbery.
edit: my bad, the way i said it made it seem like i buy the LSI cards from China. Not so. Your pro-pro-tip was warranted due to my poorly formed sentence.
