Randuin's is really great for melee champions who are trying to close the distance on your marksman, and I have also used it with some success as a pseudo-sacrifice for teammates, slowing the enemy team while I distract. Nami may not seem like a good candidate for the item, but there really isn't much else to choose from for armor. Locket is a consideration, but you'd waste CDR (at least in my build), and I'd only build it against AP-heavy teams since its aura only provides magic resist.

Seeker's also seems like a good choice, and you do bring up a good point that it's cheap and easy to get it fully stacked post-lane phase. But I personally find it to be a poorer choice and a little bit selfish simply because of its active. The AP is nice, but the health bonus from Randuin's ensures you get the most out of your armor investment. I may not do as much damage as AP builds, but I feel like being able to take some damage for the team is much more valuable then being squishier and running the risk of dealing no damage.

With that said, I might as well give AP a shot sometime. I haven't really tried AP-oriented Nami builds as much so most of my opinions are just based on observation or experience with the items on other champions.
