North American Rescue's Combat Action Tourniquet and TacMed's SOF-T are the two that I have and have been issued.
They tend to be about $30 a piece.
I don't know from experience, but based on other Asian knock off products I've used, this is not the application I would use lesser materials, fasteners, or inferior stitching. For these things to work correctly, you really need to crank on them. That's a bad time to find out the windless strap isn't stitched in very well.
