Ehh, it's not actually that bad. It might actually be the 2nd biggest prize. TAR Canada's prize is 250,000 Canadian dollars and TAR Australia's prize is 250,000 Australian dollars (both about equal to $192,000 USD)
And to actually respond to your comment about the leg's length, HaMerotz LaMillion has tended to make their final leg only one episode long (although even still, the last two seasons have had fairly short legs).
