I always get mine from HeliGuy -
http://www.heliguy.com/dji-phantom-2-vision-prop-set-new-style.html. They always seem to have them in stock.
just looked on their site but no sign of 9443 props.
just got my mail from ebay and other than the props are black, they do have the DJI logo on one side and 9443 on the other side, well balanced, spin onto the phantom super, no snagging like the clone props do, and more stiffer than the clones, just had a quick flight (really windy/gusty) and they fly great, no messing with the gains either, and for the price of £10.52 for the complete set of 4 props, good price.
I'll do a time comparison test between the clones and these when the wind calms down

well I've done a test with both types of 9443 props, genuine ones and clones.
I used the same lipo full charged each time, weather the same, hover the same and believe it or not there was no difference in flying time, (maybe 2 seconds) the only things I did notice was that the genuine ones being black but had the dji logo on, stiffer, slightly noisier, and they were very very close to my prop guards on one side of the props, bit clearer on the other side as if the nut inside the hub was not at 90 degrees to the props, so just as well I got decent clones in my case they do fly really well.
