I know some one whom spend 10K on a spider it proved to be a poor breeder and he figures that one snake has covered its meals and power but has not touched much of the 10K. It is quite likely a 200$ spider today would do better, figure you bought a breeder ready spider pair for 500$ bred then drop 8 eggs and 1300$ that covers the initial cost and food and power for all of them, next season you could make 400 or 500.

My point is if you have a bunch of money and want to see a return on it alone invest in something other than snakes it is a high risk with out good chances of large returns they do not make a good investment.
