I had mine done in Sydney earlier this year, and like you had trouble finding similar material.
I settled on a similar looking material, and had a carbon fibre lookalike down both sides.
Lookes good, feels as good as one of these poxy things can feel A$150.
I have read somewhere this week of someone doing a material as close as can be, but i am not sure if it was on the web, or a bike mag.
