Cassina 714 price
is around $2500. The 713 is probably a little less than that, since (I think) it has one or two fewer steel rods in the frame.
I have no idea what the other table costs, but if you can wait until morning, there are a number of authorized Cassina dealers who would be happy to quote you a price over the phone...
