Genuine 74F is getting hard to find. utsource used to be my reliable Chinese goto but a few years ago they moved to this Amazon model where they allow other sellers to list items including a lot who use names like "genuine utsource" and "real utsource store" with no way to filter them out. My last order with them just before Xmas was very poor (obvious remarks, shipped items from cheaper sellers other than the seller I selected, claimed a specific brand I needed but then sent totally different which had known timing issues). Their CS was maddening. I ended up getting a partial refund via PayPal.
