An Ounce of Gold is Worth A Pound In Matzah

One thing I have always wondered but have yet to find out a good answer is why does hand made shmurah matzah cost so much, especially when compared its non shmurah machine made counterpart? We can take into account that having the grain shmurah (watched since the time of harvest) is more costly than not as well as the added expense of having it made by hand instead of mass produced by a machine. But does that really add to the cost to the point where it costs six to seven times as much? By the way, all those who say that machine made tastes better than the hand made, you don't know what you're talking about.
