Its somewhere around 30/1.
For that price yea do it! Find us a place to go with a manned mission with those 30 probes!
But think of it this way as well... one manned mission can do the work of 30 unmanned missions.

Agreed, but I remain certain that there is not one damn thing in this whole solar system worth leaving this planet's gravity well for in the first place.

What about
20,000 Billion Dollars

I don't know anything about that so I'm not qualified to comment at the moment. The idea sounds expensive, but if it is cost-effective I'm all for it.

Its very cheap, I was mistaken when I said they don't need fueling just energy; they do need fuel (a gas). Xenon is a common propellant but they are doing experiments using Argon as a propellant. If you remember chemistry Argon is the 3rd most common gas found on Earth after Nitrogen and Oxygen.
