Good point but how many probes could we send for the cost of one manned spaceship?

Sometimes more distant objects are easier to get to. Less mass means less fuel needed to slow down to land on and less fuel to leave. Also some asteroids are closer to earth and the moon at some points in their orbits.

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.

That is why many birds now have Ion thrusters. As long at its solar panels are drawing power it can generate thrust to maintain station.

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.

As long as we're discussing the subject, it should be noted that it would be desireable for ion engines to be installed in tandem on spacecraft, provided they can be made to emit a really cool sound.
