IT is the same reason that HKs, AUGs, Sig 550s and others are so expensve. IT is not that they are better, just not as availible. If you want an AR15, companies simply make more. With these rifles there are simply more collectors than there are rifles. Therefore the person that offers the most gets the gun. Then the collector that bought the gun always wants to sell it for more than he has in it. If the market were open, the Galil and HK would be cheap as there were tons of HKs made and the Galil is a discontinued rifle that does not take common mags. For a collector, the Galil and Valmet are the peak of the AK design and quality.
