Well, if I'm planetside (which hopefully I am), I can at least inspect them and make sure that there are no mistakes like smartypants-McGhee up there tried. I kind of take my big contracts as they come, but if I'm too busy with work to install them I can give you a list of mechanics that are competent, honest, and won't gouge you.
Hit me back when you have your ship, though. Modding is kind of relaxing.
