Yup, fuck gravity wells, once you're out, stay out. Particularly fond of the idea of dropping a nickel iron asteroid into a near pass of the sun (yeah, hella delta-v, probably more efficient to do it in situ, but it's such a nice image) till it's cherry red, setting off a bomb in the middle to make a bubble, patch the holes, fill with air, spin it up for gravity. Quick and dirty homestead. But really O'Neill cylinders are a better choice.
