Yes it is rather low by space standards today.

It is simply the current market price for 100 kg of He3.

It is about the same cost as a Proton launch.

Let us say we use a Zenith instead (e.g. via Sea Launch LLC), about
half the price, and half the payload of a Proton.

Could that land enough of a payload to start producing a few kg per
year of He3?

And what would be the cost of developing such a processing facility?
