Unless it's a labor of love, don't spend too much on it—these Spaceliner-types are worth about a few hundred bucks complete and in mint condition, especially the step-through versions. I paid $25 for a frame for Interrobang and someone said I overpaid. After working on it, then riding the finished product, I can't quite say they were wrong. Great looking frame, though—I wish someone would remake them with modern seamless tubing and components. The TRM tank on Interrobang stiffened it up a lot, which is testimony to both the quality of the TRM tank and the wispiness of the frame. Of course, I'm 5'11" ~175 with longish legs (seat sits higher, so more torsional load on the frame) and these were made for 100 lbs women 50 years ago.
