I'd be somebody like Seaton from The Skylark of Space and build a starship in my back yard. Unlike assault, I don't think I could make an over-the-top pulp superhero with outrageous stats, piles of skills, a dicebag of Luck, perks, and a starship for 150 points. So I'd just take my crappy stats and add science and engineering skills and a starship until I hit 150.
If I don't have to pay points for the ship, I'll buy wealth.
