the pulsars of that era are pretty prone to rust, so if you do look at any, just make sure that the body doesnt have more bog and newspaper than metal. The engines are pretty good though.
Personally I would go for a corolla, or if you can find one, an early rwd corona. Those things are damn near indestructable, and if you find a jap built one with the old 18R engine in it, then it will run forever. (they also built them here with the "starfire" engine from the 4cyl commodores...*shudders* )
Also, if you can handle the shame, a datto 120Y or any of the late datsuns/early nissans with the A series engines in them are pretty reliable and stupidly cheap to fix if they do break.
