Looking at this from the company:

They estimate NPAT at 14 million for 07/08. On PE of 20 this is a SP of around a dollar, so double what it is now. And it's only growing from here from what I've learned so far. So good news for the long termers, looks like in a month and a bit nms might get a serious re-rating
