There ought to be a CWU-36(mod) with a knitted collar rather than the nomex collar, as the treated nomex is not comfy to the skin.
In Germany there's a shop that sells them for about 500 euro, which is about 650 USD.
I was happy when I could buy a new one in the US on ebay for about 120 USD, later on I got them cheaper, the cheapest one was 2 GBP with 12 GBP for shipping.
The fake ones will never have the authentic labels in it, and can not be advertised as flame resistant.
I agree, don't buy the fake ones, the real thing can be had for the same money.
The sizes vary wildly, I've got a few in Large that are way too small, a few that are spot on, and a few that should have been tagged X-Large.
The more velcro on it, the better they look, and the tan version really makes a statement.
