It's not the wrong place but the answer is difficult. The short answer is that I'd check with Zephyr Paintball or see if your local dealer can order them from the U.S. office.
The longer answer is that they have slowed stock to all distributors since around March. They've got at least one new marker (the Zii) that is starting to show up at stores in Malaysia and the UK, but not in the US yet. They also have alternate colors of the Blitz Evo set to arrive. Distribution of the Kaos and Kaos-D are somewhat dependent on when those other markers come back into shops, but it's even odds they will return when the Zii is released.
