i have always wanted one of those for as long as i have lived in singapore.
i could never find one. so i settled for an industrial blender and i keep a few packs of 7-11 ice in the freezer chest.
when the fridge broke, it was replaced with one that had an ice-making function built in (cube AND crushed - cos crushed's what i'm after!) .
i really, really hope you find one! good luck!
