If you can afford it, go for it. Lost Battalion are good quality folks. What i did, i shoot them a email regarding the field cap, they send me invoice on paypal and you pay up. Thats it. Smooth transition.
No idea if they do Straya shipping.
Godson, last time i checked, you havent joined a unit. For the price of Lost Battalion, for god's sake. Find a unit first before spending big bucks on Lost Battalion if you havent found a unit. Thats a huge risk right there.
