Some good replies, guys. It does really depend on what you want, I've had several years over the years. Square vs. round headlights made no diff in visibility, I converted a 78 wagon to 80 front end, can be done but you have to modify (with a small sledgehammer) the headlight openings in the radiator support to convert. As far as reliability, they got better as they went along, but then started getting worse again as more smog stuff was added. Major rust should be avoided. Other than that pick one that you like and go over it carefully before taking it home, they're all 30+ years old now. Good luck in your search.
