Gday HS,
As mentioned by chrisash, best place for presser feet is Amazon or eBay. I buy mine for my Consew 256 from these guys:

So far I've bought piping feet, steel bobbins, and edge guides from them. Shipping to Sydney takes about two weeks from China but the prices are very competitive and I haven't found any quality issues. Would prefer to buy locally made and sourced parts but when the price is three times less it's hard to justify.
Sewing Machines Australia are very good (I buy Coats thread from them and their price and delivery speed is great) but the price of their presser feet is off the planet.
Cheers
