Yeah, you can find them elsewhere for less money.
However, there were only 14 million (IIRC from T Lapin's book) made so that is only one for every 200 US citizens (approximate number), and we know that not every 91/30 was brought to the US for sale. And we know that some folks own a bunch, further skewing the ratio.
They will always be a collectable piece of WWII history, and they are all steel and wood which is hard to find at any price today.
Compared to other rifles of the era, $200 is underpriced due to a current market glut. When the source dries up, they will go up in price pretty quick. All the people hacking them up will feel like that was a huge mistake.
