I don't think I do. I need to look again, though. But, I figure if I've gone the last 8 or so years without then I probably don't need anything.
No joke. They're selling me used stuff and are in the middle of calibrating things (mic/laser/Klippel "box" itself). No doubt I'm going to need help. But the "extra" stuff I really want to do are what's going to add to the price; but they are things I deem necessary. I won't get in to that just yet, though. Don't wanna count my eggs before they chicken.
