I have a 670ZX and it has Auto Azimuth Alignment, it says so right on the front. It's a very nice deck and unless you're a perfectionist it should do the job.
There are still a lot of old Naks around so you should be able to pick up a nice one pretty cheap. Shop around and get one that's in excellent operating and cosmetic condition.
