I have a Kuradori Mandolin - I think it is available in the States, there is a patent nbr for US, UK. Probably more pricey than the OXO but I quite like it.
Has a case for the blades and the safety handle also becomes a lemon juicer. Like all mandolins - very sharp... my little finger does not match shape with the rest of my digits, missed the bone but came close!
I also really like the Apple Slicer/Corer by Kuradori - again, very sharp and I think the slices are thinner than other corers, which I like.
