Not all Aus Made GN's are $900aud, SK mades are only because he is the most sought after bat maker in the country and top 5 in the world, of course his work is expensive, but i would still say the non SK made bats are still a cut above the indian made bats from my experience and you can pick up an Aus made for around $400aud or less if you're bargain savy and patient.
As for the forum fad comments, its a possibility but if you make a consistently high quality product, at accessible price points that differs from the pretty generic offerings from most other large brands, why wouldnt people be talking about your products?
