I finally got 6 Lambo blades in and well... spray painted them black (ducks!) Just used a $2.99 can of cheapie paint (fiddly bits brand from Bunnings).
They were really hard to get in Australia (no one had more than 2!) but since then I found a store that has 14, with special pricing on 2 lots of 6.
They also have all of the Sian panels and I noted an orange T !!! (but too pricey for me!)
Hopefully some real black blades will be available soon, but in the mean time sprayed ones do the job for me!
