Bitmain and their Ants are definitely what all vendors should be aspiring to; good price performance and 100% legal. It goes to show that not all Chinese companies are the same and that one should be vigilant against companies like JT, JianTian, Dragon, etc who have no qualms with using stolen technology in their products.
Frankly I don't see any reason why anyone would want to purchase anything based on the A1 as currently it simply isn't a competitive option.
