I don't think they are all that hard to find in the US. I see them all the time. Most have the mums ground off which reduces my interest in them. Other than that, they are often still in their original configuration. I've also found them to be inexpensive, less than $200 and often closer to $100 but again, ground mums. Sporterized versions are also around but these for the military collector are almost worthless and I've seen these sell for less than $100 as recently as this past fall.
