It's not that bad a price depending on the quality of the alternator. Having worked 16 years as a Nissan tech, I'm reluctant to use anything on the aftermarket when it comes to alternators, starters, distributors, ignition system parts and fuel pumps. The job is hard enough to replace an alternator so you don't want to have to do it twice. There were several different alternators used on the R51s and they can range from $335 up to almost $500 for a genuine Nissan reman, but these are by far the highest quality units available. Nissan alternators are Hitachi units, so if you can find a Hitachi alternator on the aftermarket, that would be a good option. Of those listed at Rockauto.com, I would have the most confidence in the Remy remanufactured unit. Another option would be to have a competent auto electrical specialist rebuild your original unit, if there is a good auto electric shop or specialist in your area.
