mate, i dnt even think Ebonite sell them anymore...ur better off getting a second-hand one but i wouldn't bother :/ i'd probably buy a mid-price new ball like the Elevate or maybe even a Game Changer
if your really keen on an nvs, I know ebay usa has some NIB ones, also there is one at campbelltown bowl that got bought to my attention when I was looking for a total nv
