Yes, any basket case is a money pit.
However, the Crusader is a cute little bike, an they look nice.
One thing that you might not know, is that with some judicious bending of the front down-tube of the frame, a KS Bullet engine will go in there. I've read that some guys in the UK have done that, and they bend the down-tube a little, and then weld in a brace up by the steering head tube to support the angle, and the Bullet engine then fits.
It's a lighter frame, and some people like that for racing performance.
